Mainly we don't act in such cases because being stupid and useless is not actually a rules violation, and we don't run off anyone for merely being a dunce. That can of course be changed if thats what the members want, but that leaves an awful lot of subjectivity in Mod/Admin hands. I would like a "Septic Tank" or "Horses Butt" to move some worthless threads to, and its something we've discussed here before. I've even suggested "Arrowhead Stadium" or perhaps even better "The Black Hole' as a dumping ground for this kind of crap.
