I just get annoyed at seeing the spam threads and spam posts.  I don't want to open a thread at work that is inadvertently filled with porn.  Seems like we need some way to flag posts or threads that are SPAM or inappropriate.
Not to mention how fucking annoying it is to try and read the latest posts, only to see them all filled up with bullshit. 

So far I just give it a "terrible rating" and tag it with spam.
