Well, only Verified Providers can post offers in the offers forum. That is something WHT and no other forum does. The requirements are somewhat lax, but it does require that hosts posting there are operating under some form of legal and traceable entity and have things like public WhoIs.Have you thought about requiring a certain number of new threads in certain sections (i.e articles) or something like that?
I understand its a fine balance, but honestly we don't need another WHT where everyone only posts for offers.
The non-verified offer forum is more or less useless. Guests who are not logged in can not see the forum and I don't believe it's indexed by Google either. About 60% of all offers posted there never see the light of day because they're useless spam.
