Techshare is a prized cuntsmouth of a troll but I wouldn't tag him for that as he has had many successful trades and can be trusted to do as he says he will, I wouldn't believe a word he posts but I would buy something from him and be secure in the trade. Then you have the likes of TOAA, imagine a shipment going missing from him? fuck that, the total fucknugget would make the whole process so painful, so newer members need to be warned about his general behavior on the forum
Quite an example here, but yeah this is what it really looks like when people try to leave their trust rating into someone. Though on the surface a user might seem to be a troll and just spouting nonsense and making others feel a
little uncomfortable at times, IMO that per se isn't sufficient to red-tag that particular person especially if the same person has completed tons of confirmed trades, all of which went smooth and went well. Then again, you'll never know when would a good guy turn into a bad guy, so a neutral rating IMO is okay.
As for theymos having to weigh in his own thoughts into the trust system, it's best to leave it as it is. Even if the guidelines for trust-rating is stickied, I feel that some will ignore it and continue to paint someone's rating red anyway especially if they have some personal issues with the said uaer.
