I log into this server from time to time, to get some good old pvp going. Just to realise my account was banned this time?
Message on website - "Your account has been terminated due to Botting"
So I guess I've been banned for botting, but that wasn't me? The Last seen IP is from somewhere in austria so I guess my account have been hacked.
Is it possible to get my account back?
It being Terminated, doubtfully. Who was using it doesn't matter, you're still responsible for all that happens in your account, as keeping it safe is your responsibility.
