Do those campaigns pay any posts here? I mean, no sigs displayed...
that latest yobit one uses the "personal text" under the avatar
Yobit launched bumper campaign and apply the third° rule, this day most of the visit get traffic and good popularity just one day, I'm not sure but I think Yobit is a ponzi site it is just my opinion, it is true that a lot of shitcoin and valueless coin still have this site Yobit, I have no complain this signature campaign but per day 20 post is difficult for a person sometime automatically created spam, it was very better that if this campaign launched by the bitcointalk Forum member/manager.
So some issue is the End.
