This forum needs the signature campaigns to remain so active. I do not think things will change anytime soon due to this. I agree that the managers should do a better job with the useless posters though. I wish all of the campaigns were just flat rate as that would help a lot with the useless posts. I get a flat .5 per month regardless of how much I post (not that I would post more for extra pay though). It is a shame these campaigns do not just work how they should and cause all of this drama. No matter what system is put in place people will abuse it do to the incentives. You have people here that can live off of these campaigns in their part of the world.
Then people with alts will just use them in several campaigns, or people will just buy accounts to be able to post as much as before.
I think the best is ban the signature campaign if it generates too much spam, and only allow them to return if they prove they would not allow spammers
