As an example, my positive trust rating is 19 (as of now, via DT-base) compared to DarkStar_'s 54. Should I be trusted with a corresponding 35% of the value DarkStar_ typically transacts? Abso-fucking-lutely not. How much should I be trusted with at this point? Who can tell? There are no risked amounts and you'd have to develop a case file, researching the feedback and references just to determine my scam threshold!
True, counts of trust ratings don't really mean much, neither does this green dick measuring contest in general. Reading trust ratings and references etc is imperative. However if we start spamming the trust system with a rating about every fart it makes due dilligence harder for everyone.
