A quick google search shows me that this is hitting a lot of forums, so we are not alone. One forum I was just on had a problem thread about this ad that went for 7 pages of replies!

Reading through that one, it seems like this thing is VERY, VERY nasty. The admin on that forum seems to think its coming from Google and has reported it numerous time yet they are still getting hit. They seem to think the ad has done something in a cookie. I will continue to look into this and try to figure out what is going on. This looks like a pretty big issue that is hitting many forums and blogs, not just ours, and it looks like whoever is doing it is pretty crafty.
