It will take some time to recover your account even if you have all the proofs with you right now, you should contact the global moderator if they are able to lock your account, then ask campaign owners to either hire a new guy or you hire someone to take care of it or do it with an alt account. In the meantime send proofs to the admin and ask them to recover it as soon as possible.
Obviously that i want to recover it as fast as i can, payments to the members of the campaign are going to be made anyway, but i need it to be red tagged right now! This guy has changed the signature and he is just anyother newbie trying to drain signature campaign's money, that is why he probably buyed this account from someone who hacked it from me..
I can do all the proofs, i remember every single post that i made, every pm that i sent, everything.
