The reason some use negative feedback to tag spammers/shitposters is because it stands out. It's easy to spot.
The motion is there, not from me, but from theymos himself (even though the changes he is ready to make are a bit limited so far, eg "serious discussion").
I think we are at a point where the forum has to "adapt" something in order to achieve progress here. To change something, theymos should get involved and help making that change possible.
On a pure community level, this battle is lost. SMAS has little impact if there are campaigns ignoring the problem and contributing to the spam. Fighting it with less than half the campaigns is a start, but only that.
No, I dont want theymos to change the trust system to ease the work of campaign managers,
but I do believe that if theymos would work together with the majority of campaign managers on a joint effort, we could make some noticable progress in the right direction.
There's limit to the reports though (eg I cant contact campaign managers that way, only moderators, I can only report posts that violate the rules, not spam).
