Also some users will decline to trade with new users because many of them are time wasters.
Did mexxer ever pull that: I'm hero, I'm trusted, look I've been around for so long and etc bullshit? Forum status, trust, reputation should not matter when it's bought.
I don't think it is a good idea to trust someone just because they are a "hero" or because they "have been around for a long time", purchased account or not. If you do this then you are basically walking yourself into being scammed by a long con.
More concerning to me are those who engage in trades for little reason other then for the hopes of receiving trust feedbacks. These people are more likely to eventually scam, and are really not even "paying for" their trust so they have little skin in the game so when they decide it is time to scam, they have less to lose.
