Anybody know how to get rid of ths spam?

Anybody know how to get rid of the teenfirwire spam? It appears to be posting in every forum and blog on the internet.
I went to the teenfirewire website but couldn’t stand to look at all the teen porn long enough to find a support contact.
I thought file sharing, especially teen porn videos, was illegal !!! If you know how to block teenfirewire on my blog, please forward me the information.
Thanks, Sara.

I have a wordpress blog that I’m launching. That one has spam-fighting plugins as well.
