That is obviously a new campaign and would be considered a violation of yahoo's contract with cryptotalk (yobit). He may actually stop managing the campaign and most signature participants could also leave because of that.
If yahoo62278 stops managing the campaign, it's open for all shitposters again, and spammers with farmed accounts won't care if they're promoting a likely scam.
Until theymos bans their signature again.
I think this is a pretty weak argument in favor of someone getting paid to help promote a very shady company (some would go as far as to say that YoBit is an outright scam).
Furthermore, some participants may argue that they are participating because yahoo is managing the campaign.
I dont think the possibility that shitposters might spam the forum is a reason to help a scam advertise. It seems to me that the payment for campaign management services is more about YoBit being allowed to advertise without significant pushback against their participants and less about actually managing their campaign.
I have to say I am disappointed that others are not being vocal about this.
