- Must everyone be positively trusted?: My answer is No. I do not bother to build my trust list because till now, I am not involved in selling or services rendering. But I have many users here that I trust their judgement, but I don't think it's worth stressing myself about. The case of EZ0010 could be anyone else. Many users here including myself would send the money back to theymos, but because the incident didn't involve us, there's no way to prove.
The case of EZ0010 could be anyone else, but not everyone would return that money. The EZ0010 account was a newbie account with few posts, I believe there was no sentimental attachment to the account for him to want to keep it. What EZ0010 did was noble and he was rewarded for his honesty.
- Should a user be trusted because he is a quality poster?: I leave this to the community to decide.
Hint: Should a spammer be tagged? If a spammer can be tagged, it therefore means a quality poster can be trusted. Is this correct?
Then a spammer could be neg tagged for spamming, yet he doesn't have the potential to scam as he has done numerous businesses. Lolx...the mystery of trust system.
My fear about the trust system which is in accordance with 1miau: If a group of scammers upto 50 persons are working together and one among the 50 gets a positive trust. He can in turn trust the remaining 49 scam users and they inturn trust one another. Then, the trust system would be compromised.
There is nothing mysterious about the trust system. A spammer can be given a neutral trust with reference to his post spamming. I have seen accounts with neutral trust by Actmyname with reference of being part of a spammer list. It’s not a red tag, a negative tag in such situations would be harsh and will be abuse of the trust system. The person may choose to create a thread on reputation to drag the case.
