Not only casinos. There are also exchanges that advertise on the forum, such as Best Change or eXch.cx, although they advertise much less than casinos.

For January I would expect a drop in available signature campaigns, but I think that little by little there will be a reorganization, and maybe some casinos and exchanges will take the opportunity to advertise more, and also other services that are not advertised now or advertised currently as mixers that will be reinvented to meet the new rules, such as bitcoin to monero exchangers or non custodial wallets with coinjoin.
