I find it hard to believe that anyone would come to these forums only for the sake of posting genuine aquestions or providing answers to supposedly genuine questions. Life is all about give ad take. Without the need to accumulate links and get higher rankings, some of the forums might indeed not exist at all. Bear in mind how much time it takes the avarage novice to actually make an impact on the rankings of his/her site. I think some of the forums actualy depend to a certain extent on 'spammers' for their traffic.
