wow, so I read most of this and just kinda gave up on the 4th page. But I also have an idea... hopefully it wasn't already posted.
But you should need a certain amount of refs to deal or trade over a certain amount of $$$. For example... I have no refs and have never sold or bought anything here, so I should not be allowed to come on and try to sell something for like $1,000 or more or something like that. I should be forced to try and sell some of my cheaper stuff first until people get an idea of who I am... Anything involving really high numbers, you should look for a reference anyways... but some people probably dont. But if people couldn't go for an all out rip off their first try, then that would help. It would cut back on the severity of some of the scams we have seen. It always sucks to lose hard earned money, even if it is only $20 but losing $1,000 is just horrible.
