it's allowed as logn as you didn't break any rules as Lauda said on above.
paying/giving incentive to post in threads
IF we are joined in Signature/Avatar campaign, we won't get paid if we are posting in some threads which doesn't give/bring any benefit for promote their site, example: in Off Topic and Games and Round section
Off-Topic seems to be self-explanatory, but could someone explain to me why the Games and Rounds section is so much hated by the campaign managers and their benefactors? I see it mentioned in virtually every signature campaign run here as being excluded from post counts. Is it very different from, say, the Gambling section, its parent board? I never posted there myself, and I pretty much don't know the reason(s) for such discrimination...
So, what's the catch really?
Because in Games and Rounds some users would make majority of posts. And these posts are low quality, because in games and rounds users posting mainly predictions and similar stuff.
