What I should say for you today, nakamura12?
Congratulations!
You are the first winners of my challenge.

Honestly, I satisfied to most of your suggested threads/ topics, except this one.
Why?
Because, there are so many topics available on using the width option when posting images. You can search it later.
Anyway, 5/6 suggested ones are all good enough to help you receive my two sMerits.
I also checked your post history. You are definitely non-one-lined posters, despite of most of your posts concentrated in Gambling.
One again, you won due to satisfied my challenges.

You should keep up your good attitude, habits, and it's now time your turn to make others happy.

For the OP,

What do you call the forum is for the period before 2017?
Did the forum been dead before 2017?
The following time series plot (for more details, please visit the original thread to get them), shows that months, nearly one year after the implementation of merit system, monthly registered accounts have fallen to almost the same range before spamming endemic in 2017 and 2018.
The merit system launch is a shock for spammers, whislt it is extremely good for the forum.

Eventually, spamming endemic has been likely wipened out, for now.

In  my opinion, the forum has not dead.
In contrast, it has been realived.
< ... >
Notes:
It's not exact intra-month registered accounts over years due to days on which theymos scrapped data.
However, we can assumed those figures are for intra-month data.



ABSTRACT
(1) 50% of observed months have intra-month registered account range from 2311 to 27790 (the interquartile range);
(2) 50% of observed months have intra-month registered account above or below 10432 (the median);
(3) The intra-month registered account fell 91.6% from its all time high in 2017 at 238400 to 20046; whilst the bitcoin decreased nearly 83.9%.
(4) The demotion on Junior Members in September 2018 probably caused intra-month registered accounts fell considerbaly later months.
(5) The difference in means of before and after periods (cut-off timepoint is Sept. 2018) is -63.6%.


Time-series plot

There are some coincidence between plots.
The following charts show:
-   The number of historical Bitcointalk posts created between 2 different consecutive readings (*)
-   BTC price evolution in USD (source: /www.barchart.com).

Yesterday, I earned my 200th merit, so it is the right time to do something.

Here is a time-series plot of my received merits, from 28/2/2018 to 19/2/2019

It looks like a random walk.
Sometimes quietly and sparsely, sometimes intensively earned merits over the last nearly one year.
I moved much faster since early days of 2019, after promoted to a Full Member.
My target for the year is a self-made Senior Member, and I have gone two-thirds of the journey.
If the speed remains the same, I might be a self-made Senior Member next  month.
Just my hope.


For someone who feel something like "Merit ruins my life", my recommendation is:
Keep learning, and keep walking.

I have my own give-away topic there:
More than 70 sMerits available to give away (high strict rules) [Members only]
Reward rate is 2 Merits for each winner.
Nevertheless, around one week passed since the openning day of the topic, there is only one participant.
It seems that my rules are too strict, I guess, and they don't want to join, or they simply don't want to appear in my Blacklist and don't have chance to apply later.
Let's see what happen with the topic next few weeks.
If after one month, it still unable to catch attention of lower rank users, I will close it.
just advising those users begging should stop make use of GIVEAWAY THREADs instead.
8146  Other / Meta / Re: ⭐ Forum chronicle - UP Rank List - Congratulations! (BPIP Merit stat, Trust) ⭐ on: February 19, 2019, 03:12:18 PM
You should correct it.
All Junior members are self-made ones.
There is no exception.
There is no airdroped Junior Members since the demotion in September last year.
Airdroped members only can be used for other ranks above Junior Member rank.
1) Junior Members:
- AJ.
- SJ.

Agreed. Like you, a self-made Hero to come, in the waiting time to collect enough activities.
It is actually quite simple, everyone with 1000 earned merit is self-made legendary, or if there is not enough activity, will be a self-made legendary waiting for activity, same for the rest of the ranks.
8147  Other / Meta / Re: Stake your Bitcoin address here on: February 19, 2019, 02:44:32 PM
It is cool to see someone later use my guide to sign a message.
However, the third step should not be never used.

By the way, as iasenko reminded us in previous thread.
Bitcointalkers should show the proof to sign message in code or text, not in snapshotted images.
Then, people want to help you don't have to spend their time to retype all texts inside your message to verify it.
It's waste their time, and I believe they don't like it, certainly.
I signed my message yesterday and thought of it a little bit.
After all day long, I thought that it might be better (not sure about that, it is just my opinion) for forum users to sign their messages with at least four essential indicators of their accounts:
(1) Account name;
(2) Bitcoin address;
(3) Registered email for specific account.
(4) Date on which they sign message.

People tend to forget to sign message in which registered email included.
I suggest others should do that next time they sign message.

For instance:
Code:
-----BEGIN BITCOIN SIGNED MESSAGE-----
This is <your account name> from bitcointalk.org, id = <your id in the forum>,
my email is <your register email>, and today is <the day on which you sign message>
I would like to sign a message to as a proof of ownership for later use
-----BEGIN SIGNATURE-----
<Your BTC address>
<Your signature>
-----END BITCOIN SIGNED MESSAGE-----

One more tip.
Merits don't come in a row.
Sometimes, merits abundantly come in consecutive hours or days.
Sometimes, merits don't come to you, or come sparsely and insignificantly.

Nevertheless, please remember you should not pay attention on whether you can earn merits when you compose some threads.
Only composing threads if you really have something to contribute, something that has not repeatedly posted by others.
Let's take it simply by only focus on your flow of ideas when composing threads.
8149  Other / Meta / Re: Merit & new rank requirements on: February 19, 2019, 08:06:13 AM
As you usually behave, you acted very kindful.
Everyone can make mistakes because we are all human.
If mistakes are small, we all should have chances to come back.
Of course, serious violations will be the exception, and no chance to come back to compromise bitcointalk community again.
Please explain to me why you're PM-begging for Merit. I don't leave red tags for that, but only a neutral.

Never should beg for merits. It's too risky.
Quote
If you've begged others too, you're likely to receive red trust.
I'll also report the PM to Admin, chances are you get banned for a while.


Everyone who join the topic knows it.
Or if they don't know, they should spend time to read first pages of the topic and get available advice themselves.
It's good to see you tried to contribute, but next time, I suggest you should discuss if you have something new.
Best regards,
merits you have to earn yourself here. if you post good and interesting
topics merits also come by themselves. only those who are good in school
get into a higher class. so it should be . and if you are big you also
have to work to get money. that's real life. there's nothing for free

Thanks for your reapplication, Findingnemo.
You looks good, I will follow you for a while.
In the meantime, you can also edit your application with better posts/ topics.
Updated... Smiley


By the way, there is my another topic, which might be helpful.
You all can learn from those inspirational stories and users who ranked up.
Learning the way they posted, discussed, and earned merits will be helpful for you.
Inspirational stories from self-made promoted users
8151  Other / Beginners & Help / Re: Inspirational stories from self-made promoted users on: February 19, 2019, 07:55:33 AM
Update with another inspirational story.
This one comes from potential Hero Member.
I called him as a potential Hero because he earned enough merits, but have not had enough activity count to rank up to Hero.
I have achieved 500+ earned merit. (Motivational) (by Coolcryptovator)
8152  Other / Beginners & Help / Re: I have achieved 500+ earned merit. (Motivational) on: February 19, 2019, 07:50:08 AM
I congratulate you, Coolcryptovator, for your big achievements.
500 self-earned merits is amazing milestone, and it is really motivational.

Is the topic suitable to add into my topic?
Inspirational stories from self-made promoted users
I actually added into my list of inspirational stories (or motivational ones, as your words).

Personally, I have come closer to the my next big milestone, 200 merits.

I considered to open a sMerits give-away when I earned 200 merits, but I actually started before I can.
It's there, but it seems that the rules are too hard for participants, only one guy interested in so far.  Grin

In database (from theymos), the figures on newly monthly registered accounts fell hard, to almost same figures of the period 2015.

Time-series plot

As the chart shown, total monthly registered accounts in recent months dropped dramatically to the median and mean of the year 2015.
I believe that it is right time to say "Thanks theymos, merit system works and actually effective control spammers!"

Please look at the mean and median (p50) of year15 in the table below, at 24993, and 19300, respectively

To conclude, the forum has return to its quiet period before terrible spam-busrting in 2017 and 2018.
Of course, we need to wait more months to test the hypothesis.

This one is not exactly what you want, but maybe helpful for your interests.
I made it by using reliable data dump by theymos, but it is not exactly monthly statistics.
Please use it with potential biases.

As I promised yesterday, I made some quick descriptive analysis today.

Time-series plot
Basic statistics:
- Mean +/- standard deviation: 21916 +/- 34795
- Median (interquartile range): 10145 (2311 - 25509)
- Min - max: 3 - 238433.

Interquartile range (from p25 to p75 in raw result table)
Data interpretation:
- 50% of observed total monthly registered accounts (just assumed the dataset is for exactly monthly data) ranges from 2311 to 25509 (the interquartile range);
- 50% of observed months have total registered accounts above 10145 (the median), whilst the rest 50% of months have figures below 10145.

Code:
. tabstat regacc, s(n mean sd p50 p25 p75 min max)

    variable |         N      mean        sd       p50       p25       p75       min       max

      regacc |       112  21915.65  34794.89   10144.5    2310.5   25508.5         3    238433
----------------------------------------------------------------------------------------------


Data source was dumped by theymos there:
We're at a local minimum, but registrations jump around a lot:

In both medians and means, the year of 2018 has been the highest year with its median and mean of monthly registered accounts are 66895 and 64782, respectively.

- The median means that 50% of months in 2018 have total registered accounts above 66895 or below 66895.
- The interquartile range for 2018 is 36477 to 88373. It means 50% of months in 2018 have figures in range from 36477 to 88373.
I always use median and interquartile range for descriptive statistics because they automatically exclude effects of outliers data points.

I saw some guys got bans to wear signature for years.
Which types of forum rules' violations lead to such year-lasting bans?
Thanks.
8156  Other / Meta / Re: How can we take Bitcoin Talk back into the Bitcoin community? on: February 18, 2019, 03:24:08 AM
As I promised yesterday, I made some quick descriptive analysis today.

Notes:
It's not exact intra-month registered accounts over years due to days on which theymos scrapped data.
However, we can assumed those figures are for intra-month data.



ABSTRACT
(1) 50% of observed months have intra-month registered account range from 2311 to 27790 (the interquartile range);
(2) 50% of observed months have intra-month registered account above or below 10432 (the median);
(3) The intra-month registered account fell 91.6% from its all time high in 2017 at 238400 to 20046; whilst the bitcoin decreased nearly 83.9%.
(4) The demotion on Junior Members in September 2018 probably caused intra-month registered accounts fell considerbaly later months.
(5) The difference in means of before and after periods (cut-off timepoint is Sept. 2018) is -63.6%.


Time-series plot

I don't know where I snapshotted the image, due to lack of thread's author, LOL. Still found it and will post link of the thread later (if I can find it). If you can help, please help me to find the thread.
I actually spent around 15 minutes or more to check back the first 80 pages of Merit & new rank requirements topic. 80 pages made within 3 days after the start of merit system, most of them are pyramid quotes. Honestly, my fingers got hurted due to over-scrolling computer mouse, so I gave up for now. Wholy shit, pyramid quotes!
Scanning pages again, still not found on page #130.  Roll Eyes

Someone else's thread similiarly describes what the time-series plot above shown.  Grin

As the chart shown, total monthly registered accounts in recent months dropped dramatically to the median and mean of the year 2015.
I believe that it is right time to say "Thanks theymos, merit system works and actually effective control spammers!"


Basic statistics:
- Mean +/- standard deviation: 22200 +/- 34774
- Median (interquartile range): 10432 (2311 - 27790)
- Min - max: 3 - 238433.

Interquartile range (from p25 to p75 in raw result table)
Data interpretation:
- 50% of observed total monthly registered accounts (just assumed the dataset is for exactly monthly data) ranges from 2311 to 27790 (the interquartile range);
- 50% of observed months have total registered accounts above 10432 (the median), whilst the rest 50% of months have figures below 10432.

Statistics over years
In both medians and means, the year of 2018 has been the highest year with its median and mean of monthly registered accounts are 66895 and 64782, respectively.

- The median means that 50% of months in 2018 have total registered accounts above 66895 or below 66895.
- The interquartile range for 2018 is 38393 to 88373. It means 50% of months in 2018 have figures in range from 38393 to 88373.

Percent changes of intra-month registered account:
The figures decreased 91.6% when bitcoin fell 83.9%.
It gives us a potential causal inference that implementation of merit system and new rank requirements have bigger effects than the falls of bitcoin.
One more finding, the intra-month figures after September of 2018 (Junior Member demotions) fell significantly than the before period. I think it make sense.

Detail calculation presented below.
Code:
* BTC price
. di (19800-3190)*100/19800
83.888889
* Intra-month registered accounts
. di (238400-20046)*100/238400
91.591443

The means of before and after Sept. 2018 are 80179 and 29190 (respectively)
The percent of difference is 63.6%
Code:
. tabstat before after, s(n mean sd p50 p25 p75 min max) c(s)

    variable |         N      mean        sd       p50       p25       p75       min       max
-------------+--------------------------------------------------------------------------------
      before |         9     80179  30633.52     83999     61360     89659     41451    136872
       after |         3     29190  7570.575     31502     20733     35335     20733     35335
----------------------------------------------------------------------------------------------

Code:
. di (80179-29190)*100/80179
63.593959

You acted so fast, LoyceV.
A brand new topic: https://bitcointalk.org/index.php?topic=5108184.0, it's on my Watchlist now.
It abusing a brand name and logo, and already has 3 active shill-accounts bumping it, all registered today.
Pumperboy, the name of one of these three accounts make sense.
It is likely created for pumping services, I believe.

Additionally, the answer of OP is ridiculous.
We use the logo only to attract attention on the pilot site

It is interesting to see such speedy listings for Grin Coin and amazing supports from former biggest exchanges, Poloniex, then Bittrex.
They all actually realised the big potential of Grin coin.
By saying about potential of Grin for exchanges, I implied about the coming trading fees from Grin coin.
The coin has high demand from community, so in long term it will contribute significant trading fees for exchanges on which it got listed.
