And I don't know about secondstrade, but yobit bans people that only post crappy posts, even if they are slow sometimes.
Last wave of bans:

(users who post laregely rubbish)
Those are just a small selection of users on yobit and he is slow to react or doesn't at all. I've contacted him several times about shitposters on his campaign but even if they do get kicked off they just move to secondtrade until they're a Full Member then on to one of the higher paying campaigns and if none of them accept them they sign up with bitmixer who have automatic sign ups. Yobit hasn't even responded to my last messages either but it's not enough to just kick people off two weeks after they get told about them. They wouldn't even know about problem users or care about the quality of posts they're making if someone didn't tell them about them and countless new shitposters are signing up daily. They shouldn't be accepting or paying these users at all and nothing is going to change without some involvement from them to actually start managing the campaign which they clearly are not interested in doing.
