I think by now you should have known the nature of people behind cryptotalk and yobit. They don't really care about people's please and do whatever they please.

If you feel the campaign is a waste of your time, don't bother doing it and you won't have to be heart broken by their ever-changing rule.

Personally i would never sign up for the forum because honestly, there is no better forum with constructive crypto discussions like bitcointalk. It tried out bitcoingardern  about a year ago but i didn't even last 3 days there. It was so boring as hell
