forum spam is out of control -- why?????

This used to be a useful forum for exchanging bicycle info on rides, for sale, and general discussion.  Now the forum is a SPAM magnet! What's going on here?  Is anyone in charge of this forum, why does the Cascade forum attract and display spam?  I belong to a half dozen other internet forums and the spam problem is non-existant, but here it outnumbers the legimate posts.

Is anyone from the Board of Directors here that can address this?
