Yobit signature guidelines just says that they will not accept -ve trusted members but in reality they are accepting and paying it. So Yobit campaign will go on with red tagged users (as they have nothing to fear as they are already tagged and forum is not going to ban them).
I think there is a bug as they sent more payment then they amount they wanted to give, later they fixed that. And on the same way, they will fix the bug of negative trust too then no negative trusted will be paid.
