Dude, If you haven't noticed. Go look in the Theft Report Forum. You have kids saying "Your a scammer." and they reply "No, You scammed somebody out of a tank"
Its an endless case. You can't really tell if somebody scammed somebody. You have to rely on somebody telling the truth. Also, People have lives and they might not ship it one day and the next day somebody calls them a scammer.
Also, They can make as many names as they like. The mods can B.O.S them. Their IP address shows up everytime they join.
