This is not my personal issue, but other people have trouble trading without getting scammed.
Even if you, ko4life admins, caught a scammer, banned him, his IP address, and his account, all that a scammer would need to do after being banned is create another account. With that account, they can view the market sections and post there or send PMs to people they want to trade with. And even if you did enact this post count rule, they could log on another account to scope the market sections and send a PM through the forum on their newbie account.
I suggest that you force them to get 100 posts before allowing a new account to send private messages or look in the market section. Scammers would have a hell of a time getting their posts up so that they could view the market section and send private messages. This needs to be enacted now. People are getting scammed by the hour.
It is human nature for people to displace blame, and that blame is being placed on the forum moderators/admins.
