The reason OP wanted to contact them is to get paid for using their signature. He doesnt have a real problem...
Of course, I still see some guys wearing Yobit and they are not posting that they are getting paid, they are earning in their dashboard but you can't transfer to their balance, after the last campaign I don't think they are going to do a bounty campaign here, they will wait to ease up and maybe they will implement new rules and guidelines, the current one sucks.
