Not everyone spams to 50, some people actually use the time to research the forums and post considered and insightful contributions to the community discussion. As I have said before the 50 post rule isn't going to be changed anytime soon and do not be surprised if the newbie forums gets cleaned up at some stage, just because spam is tolerated in there at the moment it may not stay like that way forever.  I appreciate the 50 post rule is not universally popular but from a mods perspective it has made keeping the forums spam free a 1000 times easier.
