All of them seem to be asking questions about something Bitcoin/Crypto related.
Let's ban everyone who is asking crypto related questions on bitcoin forum. Sure.
Just create a board for new members. You know it will have to be done sometime, so the sooner the better.
I know that something like this is already working on Russian local section where newbies can't create threads anywhere excapt newbie section. But tbh I don't think it could be appliable to the whole forum because some services are creating their accounts and have to start their threads asap (but btw allowing thread creation to copper member newbies might help here).
