I'm late to the conversation- but I'm pretty disappointed this ban took place. Signatures have always been a topic of controversy and I've always been a strong proponent...
Theymos did not ban all the signature campaign and you can still participate on it including yobit but after 2 months from the ban for this one.
It is the fault of yobit, they should hired a manager or at least selected/limited the number of eligible participants.
@safar1980 : lock the topic, it is already solved.
