I can tell you for a fact that majority of the participants of the campaign don't care promoting for weeks
Let's be honest here; of course they don't care as majority of them are shitposters and they are aware that they wouldn't be able to join any other signature campaign that pays in BTC.
Totally not acceptable. However it can also easily be avoided by not joining any of his sig camps. Not like him? Don't join his sig camps.
Exactly. Any self respecting person shouldn't join his campaigns as long as he continues his behavior. If you join his campaigns, it means you deserve the treatment you get. Look there are people that joined yobit campaigns and treated by the other members horribly. 1xbit participants got even a worse treatment. When you are making a decision, think about the possible outcomes. If the outcomes would affect you in a more negative way, then don't do it. It is that simple.
