I feel that sig campaigns hurt this forum and should be either banned or have serious rules.
All that we get to see from those campaigns is spam, bots and low quality posts. This hurts the forum as a community because with low content quality you don't get constructive threads, a lot of posts get ignored and in the end even campaign owners don't get the best out of it from such community.
Poor community will repel all good members.
It is like a paradox, the better te forum is, you get more good paid campaigns. With good campaigns there come the shitposters which make forum low quality. Low quality forum leads to no campaigns and no campaigns will result with less shit posters and return of the more quality.
I am not sure if in practice works like that but hopefully we won't get into low quality spiral. Merit system and strict rules seem to help a bit. Forum has a lot of publicity, history and quality members and with some time I hope we will see bright days.
