First of all, this thread is over a year old. Secondly, your best bet is to PM Dooglus and ask if he would consider a Neutral instead of the Positive.
I sent Dooglus a PM asking him to reconsider his positive trust.
I was just curious how the trust system works because it is strange to see a scammer have such a high trust score, and thought it might be a glitch in the trust system.
10 is not a high score. Its the highest one can get for a single rating, but that comes with age not with trustworthiness.
