Not really, the Campaign has a running 60 day ban. The two cases presented above are really a prior version of the Yobit Campaigns signature, from some point in the past. Notice that both @Dudeperfect and @alyssa85 have a Yobit signature that refers to "over 350 coins". The current (banned) signature references "over 1450 coins".
There are a handful more profiles Ive seen still bearing that old version of the signature.
For real i saw @Dudeperfect with something like a "Yobit.net signature is banned" on his sig space earlier on unless i was hallucinating There are a handful more profiles Ive seen still bearing that old version of the signature.
Maybe what's happening is the yobit chaps have found a way of encouraging users to wear old yobit signatures that have yobit.io link which was not banned whilst displaying Yobit.net on the signature for people to see
