Extended to PMs and many other boards (Trading discussion and subsections, Mining and subsections, Newbies, alt cryptocurrencies, and some local sections).

Let's see 'em block this. There's now a random number of invisible "posts" before and after the ad, and they're all (I think) indistinguishable from real posts if you're limited to just CSS selectors. Hopefully the filter maintainers aren't careless or they'll end up blocking random posts.

Nah, then I'd have to worry constantly about keeping the email service working.

One person in your trust network can increase the third number to infinity (maybe literally). The fourth number in parenthesis can't be manipulated so easily. It's a rough approximation of the number of trust points from distinct users per month. So if I rate someone 3 times in one month and 3 times in another month, the fourth number should be 6. But if I rate them 1000 times in one month, their fourth number should be ~5. (But it's actually only an approximation of this.)

I needed to get this number for the trust score anyway, so I thought I'd include it.

The trust score is currently calculated like this:
floor((min(fourth_number,10*months_since_first_positive_report)/10)^2*months_since_first_positive_report - distinct_scam_reporters * scam_factor)

Where scam_factor starts at 0.5 and increases by 1 if the newest scam report is less than 7 days old and by 3 if months_since_first_positive_report is less than 2.

It will be more clear in a couple months whether this is a good algorithm. I'll tweak it more then.

Fixed.

In order to collect more money for the creation of good forum software and for other useful purposes, the forum is selling ad space in the area beneath the first post of every topic page.

Ads are allowed to contain any non-annoying HTML/CSS style. No images, JavaScript, or animation (no marquee or blinking). Ads must appear 3 or fewer lines tall in my browser. Ads will be prefixed with "Advertisement:". Ad text may not contain lies, misrepresentation, or inappropriate language. Ads may not link directly to any NSFW page. Ads may be rejected for other reasons.

There are 10 total ad slots which are randomly rotated. So one ad slot has a one in ten chance of appearing. Seven of the slots are for sale here. Ads appear only on topic pages with more than one post, and only for people using the default theme.

The ad lasts at least 7 days starting from when I put it up. (However, if you look at the ad history you'll see that ads frequently get 1-2 extra days, but this is random and definitely not guaranteed.)

Auction rules

Post your bids in this thread. Prices must be stated in BTC per slot. You must state the max number of slots you want. When the auction ends, the highest bidders will have their slots filled until all seven slots are filled.

So if someone bids for 7 slots @ 5 BTC and this is the highest bid, then he'll get all 7 slots. If the two highest bids are 7 slots @ 4 BTC and 1 slot @ 5 BTC, then the first person will get 6 slots and the second person will get 1 slot.

The notation "2 @ 5" means 2 slots for 5 BTC each. Not 2 slots for 5 BTC total.

- When you post a bid, the bids in your previous posts are considered to be automatically canceled. You can put multiple bids in one post, however.
- All bid prices must be evenly divisible by 0.25.
- The bidding starts at 0.50.
- I will end the auction at an arbitrary time no more than 12 days from now. (I will probably end the auction 1-3 days before the ads are scheduled to go up.)
- If two people bid at the same price, the person who bid first will have his slots filled first.
- Bids are considered invalid and will be ignored if they do not specify both a price and a max quantity, or if they could not possibly win any slots

If these rules are confusing, look at some of the past forum ad auctions to see how it's done. I also post periodic status updates which should help make things clear.

You must pay for your slots within 24 hours of receiving the payment address. Otherwise your slots may be sold to someone else.

From this round forward, hero members, Donators, VIPs, and moderators will have the option of disabling ads. People who don't see ads due to this will obviously not count toward the number of impressions. This option is buried in the profile settings, so I don't expect this to affect impression stats or ad efficacy significantly, but I'll guarantee at least 420,000 impressions per slot for this round.

Auction ended. Final result:
Slots BTC/Slot Person
1 6 Xian01
1 6 BitcoinVideoPoker
4 5.75 Inaba
1 5.5 paul3

QC doesn't break SHA-256.

OK.

Yeah. It'd also be better to be able to give a score to each person on your trust list which limits how much their ratings count toward the scores. But the current system is a lot easier and more efficient. It'll be good enough for now.

If you don't want to trust anyone, trust someone with an empty trust list (satoshi, for example).


Yes. Consistency is very important for determining whether someone is trustworthy. Currently, your trust score will go from 0 to 1 when your oldest rating is one month old and you have 10 positive rating points. I might change the algorithm, though.


Anyone who will give useful ratings and will themselves have a good trust list. My most important consideration for my list will be choosing a trust network that doesn't have any incorrect negative scores. This will be especially important for the next few months while everyone has low trust scores. Currently, only one negative rating will result in a warning on the person's posts (each negative rating reduces the trust score by 0.5-4 points). This won't be the case after 2-3 months.

The trust system will replace scammer tags for most scammers, but it's weak against scammers who were previously very-trusted (like pirateat40), and maybe also against scammers who scam only one person in 100. I will continue giving scammer tags in these cases, at least. I've also been thinking about using scammer tags as part of an arbitration system, but I need to think more about this.

If troll ratings start getting into trust networks that matter, I will do something to fix the system. I don't think that this will happen, though.

I changed some things:
- The third number now takes into account the risked BTC as well as the number of trades. For every 50 BTC people have risked with you, you get one extra "trade" added to your trade count.
- Added sent ratings to ratings pages.
- Added trust network list to https://bitcointalk.org/index.php?action=trust

Yeah, I will add that soon.

Go ahead.

That'll resolve itself after a short while.

It means that the difficulty of mining a block is 11,187,257 times harder than it was when Bitcoin was first created.

I will probably publish the entire trust network at some point.


I can add it to local sections if the local moderators want. I won't be able to translate the UI now, though.
