Writing lengthy posts without any substantial content is there since the dawn of signature campaigns.Often,such posts are mistaken for "Quality Posts" which they aren't.However,good campaign managers like Lutpin/Lauda that I'm aware of don't really care how long a post is if it's constructive.
Not going to mention names but there are still campaigns filled with such lengthy use-less shit-posters.I call it "progressive shit-posting".
It is true that signature campaigns made people write longer as well but I think with the merit system they write longer than before and with a structure that tries to appear as quality.
By the way, is that thread reportable?
