I don't think so. Those topics are discussing Bitcoin, so they have their place here. It has now the same function as the new "Gambling discussion" section.
No, they are not discussing Bitcoin dircetly. They are discussing useless general stuff that isn't Bitcoin specific (and/or personal experiences), which could also be answered properly within the first page. Such posts are extremely useless in most cases and just end up wasting your time reading through them. They should be moved into Off-Topic at least, or optimally locked and forbidden.
Maybe we should have some spam fighters? Like, fight fire with fire? So whoever created the topic we just have 100 people send them 5-10PMs a day saying "lock your useless thread *link* or the spam to your inbox will continue.
