@Tambu it was not ban, but if you creating account with VPN ( on evil ip ) you are unable to post
and you need to pay a little bitcoin to able posting.
Of course, if you are lucky enough (happens frequently with Tor), the IP will be blacklisted. But this only happens when you are creating a new account under the blacklisted IP. After paying the fee and registering (or just logging in with your existent account), you can login to the account normally.
Thanks TryNinja for clarifications. Yeah I misunderstood it.
