One simple solution is to require developers with minimum number of feedback, and few number of mods to sell $20 mods or cheaper only, until they reach lets say x number of points, or feedback. then they can be relatively trustworthy.. Developers with excellent feedback will do anything to prevent that feedback to be tarnished, meaning refund money to customers, provide quick support, etc.. If complaints start rolling in, account suspends automatically.
