Well, you're right about this. Perhaps, we can only allow people with at least 1000 posts (quality ones of course) and above in order to create any new threads in the trade zone area. Not sure what the mods think about this but some forums are implementing such a rule. It's nothing new but at least, it will reduce a number of scammers here as they definitely wouldn't want to post 1000 times here before they're able to scam an innocent soul.
