Title: Changes to how Scammers' trust scores are calculated? Post by: Quickseller on February 23, 2015, 06:04:23 AM Has the way that the trust ratings are calculated changed?
While looking at a scammer's trust rating ( GoldBits (https://bitcointalk.org/index.php?action=profile;u=454486)), I see that his trust score is "-50" or -50: -9 / +0(0) when looking at it from my account that uses a "corrected" trust list, and -39: -7 / +0(0) when looking at is from an account with a trust depth of 2 and only trusting DefaultTrust (which is the default). Additionally I see that TF's (https://bitcointalk.org/index.php?action=profile;u=67058)trust score is -830: -19 / +21(21). I know for a fact that in the past TF's trust score was both negative and in the four digits, and he has not received any positive feedback recently (this is looking at his trust from an account with a trust depth of 2 and only trusting DefaultTrust). I know in the past that once a user gets 4 or 5 negative trust reports their negative trust score increase exponentially (the absolute of their score increases; the actual number goes down a lot). After doing a bit of research, it looks like this (https://bitcointalk.org/index.php?topic=337207.0) is the most recent formula for calculating trust scores: Code: scam_reports = total unique users who report scamming I am not going to attempt to calculate what TF's score should be manually, however I am confident that it was lower very recently. If this is not the most recent formula for calculating one's trust score, can someone please point me to a more recent formula? Title: Re: Changes to how Scammers' trust scores are calculated? Post by: hilariousandco on February 23, 2015, 06:19:00 AM I think it decreases a little over time. When someone is flooded with loads of negatives their trust score will be very high but will fall down a bit after a short period (not sure on the exact figures/times).

All of GoldBits's negative trust reports were made today. As per the above formula, unless you are a long term con man (e.g. have more then 4 negative trust reports) then reports less then 7 days old are counted 1.5x what they would otherwise be worth Title: Re: Changes to how Scammers' trust scores are calculated?

I was really tired when I made that thread and found a few grammar mistakes when I first posted it.What if theymos has updated the trust formula but hasn't posted here? -MZ I am pretty sure the trust calculation for scammers has probably changed somewhat to prevent scammers from continuing to troll to try to get the 'worse' trust score |
