I'm part of YoBit.net signature campaign but I'm not currently 60 days banned. I think it depends on the user if really spamming because of participating yobit signature campaign.
If I understand what Theymos did correctly, he banned members who'd had a post reported as spam against them marked good within the last month (?), but
all Yobit sigs are disabled regardless of whether members got a ban or not. So you obviously did not get banned, but you can't wear the Yobit signature for 60 days at least. Who knows what's going to happen after that. Yobit might rethink their decision to resurrect the campaign.
so far, yobit bounty look like promising for all bounty hunter.
Umm, given that a lot of them got banned and Theymos basically banned Yobit from advertising temporarily it doesn't look too promising to me. It actually looks more promising for the forum itself right now, which personally I'm happy with.
