I don't really like to contact Google for the same reason I don't like to contact Overture -- you tell them about something, and then all of a sudden they're reviewing your account and they edit or delete something. What I'm hoping, and expecting, is that this happened to someone else, and they'll be contacting Google. I like to stay under the radar with these folks, too unpredictable, even when you do everything they tell you to do. Easier to just disable content until the IP is removed from AdSense.
Thanks.
