Feel like going hunting?
Go check your sitemeter for Level3.net IPs showing up from Florida. This bit of encrusted, sun-dried, chicken shit has been spoofing URLs in many blogger's comments.
How can you tell? If you get an inscrutable or noxious comment from an otherwise lucid blog personality (I know, that is the tough part!) go hunting for Level3.net IPs. If you can check their outclicks, you'll know where next to go find scurrilous comments attributed to you or someone you know.
Some scum-bot out of central Florida has been playing in the Fields of the Bored, leaving evil comments, trying to start something. Today, the feed is coming from Inglis, FL. But it could be Gainesville, Williston, and many other points up and down west/central Florida. Likely someone/thing from the State Penitentiary?
Here's a good list to start with, so start banning with abandon:
If you see your IP here, get bent.
