The spam here isn't much worse than any other forum I visit. Check out the Steve Jackson Games forum sometime.

With that said, I *hate* the fact that so many users had trouble joining the site for so long and I'm thrilled that so many new voices have gotten to join. I am quite okay with having to delete a little spam here and there in exchange for bringing new blood to the site.
I would, however, like to eventually see user permissions set to such a way as to restrict how much new posters can post. It's a pretty common practice and I think it would help curb most of the spam.
