Scams are not moderated, the section was put in place after the ponzis made the rest of the gambling section useless.
Edit:
The rule(s) for a sub section are essentially "have enough threads/posts to make it a dominant topic in an existing section". E.g. blockchain.info might get a seperate section if the support posts are too much for the service discussion section.
Might "8ball of Meth and Rusty AK47 Gift Set" get a separate section if the support posts are too much for the goods section?
If not, why

...I think Investor based is a useful sub forum. ...
As useful as any ghetto, i suppose. The problem's the public face of Bitcoin is now a ghetto.
Grills are laughing.
