[Experimental] Bitcointalk quality score

[fillippone]

After thinking about it a bit more, I think inactivity should reduce the quality score more than just based on posts in the last 120 days. Did satoshi do good things? Yes! Is he a quality poster? Well..... He's not even "a poster"! Users like nullius or n0nce made good quality posts, but they were just a blip on Bitcointalk's timeline.

Something that separate a blip on Bitcointalk history and a true legend is the amount of merits received during inactivity.
Merits received by users like Satoshi, Hal or o_e_l_e_o while they were inactive are a testimony of their greatness.
Maybe a merit received while inactive should count more? I am sure some shitposter got merit while inactive as well.

It's going to be really difficult to put all possible scenarios in one formula.

That is for sure, and hopefully is clear to everyone.

Interesting approach: a penalty for being inactive, but a bonus for still earning Merit

@OP: How is Symmetrick going to get a fitting quality score?

I think it would be more informative to assess the quality of each individual post rather than show the ballpark figure, but unfortunately no script can really do that because it relies heavily on human cognitive ability. So we use our own judgment instead and reward the posts we like with merits. Besides, I’m very reluctant to overload my browser with extra, non‑essential scripts. The fewer scripts the better browsing.

Wonderful idea *ace*
I can't say whether it would be feasible to create an algorithm capable of providing a definitive assessment of quality!
It would certainly be an excellent indicator! I have faith in you, as you've had some great ideas with your small projects so far.

If it goes well, this experiment could provide valuable feedback on user quality! But it should not be misinterpreted: the tool does not judge what we write, only the data available.

No matter the disclaimer you put, it will almost certainly be misinterpreted by many.

Gotta be honest, I don't like users being judged by merit earned as things are more complicated than that and as LoyceV said, its going to be very hard to cover all the possible scenarios.

I think the idea os good, but we already have so many features in the profile:
Merit, trust, activity, and even other very good third party indicator (bpip rank)

I think bpip is good because it does cover everything somehow...

I have made some changes to the formula.
Now, new members who have few posts but many Merits are not ranked higher than those who have many posts and many Merits.
Furthermore, the longer a user is inactive, the greater the penalty on their score.
The tool now gives us three pieces of data
Final Rank: this is the overall score that summarises history + recent activity.
Reliability: This is a measure of the user's stability and consistency calculated based on the total number of posts
Profile age (how long the user has been active)
Reputation Score: This is a historical measure of the effectiveness of posts and Merits received, regardless of recent activity.

This is actually a nice move with an added advantage to the new.. as I believe this is first thing that is introduced as the beginning of this year 2026. Well, this is nice and I would also want to know my score level.

Please if there is possibility do not hesitate to post it here for me let me view my score as well. Again I want to also where this can be useful on the forum or where to use it when there is need for it.

exactly, and when you're done, as I proposed to Vod for his very nice project I can audit the code on github
I thought with him, but it goes for you too Ace

Baboooooooooooooooooooooooo, if you plan on doing this to gain reputation and start a service, you should create an account on github and the other platforms.

Very interesting tool, congratulations on the dedication to build it and share it with us. Regarding quality, I can say that this is quite relative and there are countless variables involved. That said, I believe that the vast majority of people who are more active forum users know each other well, after all, we are practically always the same people around here, and this creates an organic quality baseline where everyone knows who is who.

Therefore, it might be interesting to leave part of the tool customizable (I don’t even know if that is possible), so each person could personalize it according to what they consider to be quality or not.

I looked at the code, he left a link on where to install the userscript via Tampermonkey or Greasemonkey. I saw that he released it under an MIT licence, and if I'm not mistaken, the MIT licence allows others to use the tool and modify it as they wish. I don't want to be wrong, but that should be the case.
So anyone who wants to can customise it as they see fit, but it wouldn't make much sense to change the formula. We might as well discuss it here and give feedback to *ace*.

This high score is the reason I asked It should be something like "-999 -- Former Elite"

I already have an account but it's a private one if we want, maybe it's better if I create a dedicated account for this
yes that's a good idea... I could also call him babu with pronunciation babooo

Since I understand malware and am a senior in javascript, it's a no brainer for me to check the code..

ok done.. my account name is babo-bt

The formula will penalise him even more if he does not become active again, but it will not bring him down to zero; it will stop at a maximum of 10% of the total.
See satoshi for a better understanding.
It does not seem fair to me to remove all the points. For better or worse, these users have been part of Bitcointalk's history, so I must give them some recognition, even though I do not know either of them.

Try to find one good post made my Symmetrick, you'll see what i mean

What the hell? The posts are all empty and archived!
How can he have all these Merits?
Unfortunately, however, it is not an error in the formula! It is a borderline and isolated case, I would say.

Let's keep it short and say he went full drama, and burned his reputation and contributions.

I'd say this is something your formula should account for. I just don't know how, other than manually adding exceptions.

Tell me if something like this would work:
Post120 === 0
Merit120 === 0
Inactivity > 2 years

Final score = 0 dormant former elite
Reputation score = score given by the formula

[LoyceV]

Merit120 === 0

One Merit would mess it up again for 4 months.

I did an evaluation of this greasemonkey script (by preferred app) Bitcointalk quality score — Greasyfork


- Limited Permissions: The script correctly uses GM_xmlhttpRequest... goood
- Clear Namespace and Authorization: Metadata (@name, @author, @license MIT) are defined.. double good
- No Obfuscated Code: The code is readable and not obfuscated, allowing for a complete analysis... triple good
- Error Handling: Includes try...catch blocks and handles error cases in API calls, avoiding visible crashes, good x 4
- Be aware that you are trusting bitlist.co to read some of your browsing data, but bitlist.co is safe, so ok
- The script reads public data (posts, credits, dates) from the Bitcointalk profile page and sends it to bitlist.co to calculate advanced statistics. Bitlist.co is safe, so it's ok; just reminder There is no direct risk to the security of your account, but this operation may not be in line with your privacy expectations.



for me this code is ok
