There are always going to be ways to counter something. However, if you do this then you should be permanently blacklisted. It would also get detected quite quickly IMO.
Anyhow, what I'm proposing is an "all-out attack" of the problem:
1) Stricter evaluation and bans.
2) Ban users.
3) Ban managers.
4) Ban services.
5) Negative ratings for all 3 groups.
If you aren't willing to work towards a better environment for everyone, and you are actually making it worse, then why should anyone tolerate you?
Banning users should indeed be the top priority, and not the managers.
I am quite active here and stumble over all the broken English shitposters, account farmers (which mostly are not enrolled in a campaign) that are posting 3 or 4 times in a row in the same thread with their alts in just a matter of 10 minutes or so, and still I keep seeing them every day shitposting again.
It's too obvious that these people are active, and I'm not the only one that is able to spot them. But the fact that I see them everyday doing the same, just shows that the ban hammer isn't being used enough.
I pointed out a few accounts to you Lauda, but the person operating these accounts is still shitposting with his over-obvious way of writing and sentence line up.
Assigning personal responsibility to campaign managers in regard to what users enrolled in their campaigns post should work better. Kicking a spammy user from a signature campaign would most certainly make him stop posting altogether without banning him directly. Die-hard spammers who are spamming regardless of whether they are wearing signature or not should be the mods' concern, of course.
