I have not looked around in Invites & Accounts very much, but have reviewed Digital goods a couple times over the past few weeks. Each time I visited, the first three or so pages were full of transparent scams and likely money laundering schemes. Oh, and CSW is apparently trying to buy some old wallets, but some people consider him to be a scammer.

I don't think it would be a crazy idea to close or somehow restrict Digital goods to solve this problem.
