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.
The sub forum was made to gather all ponzi scams in one place so people know that those ''games'' there are definitely ponzi and if someone tries to promote a ponzi somewhere else the thread will get moved to the investor based games. There is no way to stop ponzies from showing up, if mods deleted them people would just promote them without telling people they are ponzies so we would actually create more scams.
