Here is another idea.......
Since this is NOT intended to be a PRIVATE forum and new members (and potential scammers) can just pay their way in........
Perhaps a rating system or feedback system to allow buyers to leave feedback for sellers/traders/whatever. Rating systems are only so-so but it might be worth a sub-forum. Word of mouth travels pretty darn fast in these forums and a scammer would show up rather quickly. And, the cream would rise to the top of the ratings.
Again, just tossing things out.
EDIT: A system like this could possibly be automated by using a special "LIKE" icon. I can like or love or laugh at a post automatically and the puter keeps track. Maybe add another "LIKE" icon that identifies a good trader/seller.
