Spam on forums

I've noticed of late spam on the forums. Especially the iPhone forums has increased greatly.

Most of the spam seems to do with the same thing (TV shows/sporting events streaming). So it appears to me it's the same person/s posting, unless suddenly every spammer is into the streaming business.

I say Macrumors should take a stricter stance against the spammers. Instead of just deleting posts/blocking againsts I suggest the very moment someone is caught spams the forums, their IP address/es should be blocked from ever visiting Macrumors again. I know this may be difficult and would require a bit more work by the moderators.

Thoughts? I'm just sick of this spam, it's not THAT invasive but it does clog up the forums abit.
