Account farming is not worth it, months of making a post a day to keep up with the potential activity and at the end of the day, all you end up with is a measly 0.5 at most
what if the account is only made for games and rounds section? so the post can still be seen as spammy/insubstantial?
not spammy but insubstancial
Nobody can give you a guarantee that they wont be banned but that is down to you. Make decent/relevant posts and you can have as many accounts as you wish either on signature campaigns or not, but if you make poor spammy posts you risk having them all banned. I wouldn't just make posts exclusively in off topic though either. If you want my opinion it's not really even worth the time and effort farming accounts now as you get so little for them in comparison. It would be best to just use them for signature campaigns instead.

i doubt it, how can someone make substantial post in giveaway threads?
