So them being the reason behind a user's negative tag is fine for them, knowing that those users will never get their tags removed and got their account ruined while also trying to enroll more in order to get their cheap advertisement done at the cost of those accounts' ruination is truly unacceptable and should be stopped because some good members may fall for this, at most for the reason of any specific IRL emergency or whatever reasons. Pity for them who join such campaigns.

Anyways, I don't think there's any reassessment needed for busted accounts as well as spammers and scammers because even if trusted and given another chance, the greed in them so provoke them to continue committing the same "mistakes" they've done so far. I believe that those who got active recently, got their email or password changed immediately after that should be scrutinized and checked because many of such accounts were found guilty as bought accounts in order to participate in signature campaigns (or if an account is bought that has green trust, it can be much more dangerous to the community).
