Mine's down even further. (I can tell that it's down, Mario155, because this site gets very little direct traffic yet, mostly search engine, and it's targeted to one particularly state, and the direct traffic is coming mostly from Europe and other states)
Goofiest thing I've seen in a while. I got no explanation. No, I never heard anything from Google after I gave them a few sites to look at (but I didn't really expect I would) There's nobody to report it to, because there's nobody in charge of such things, nor any clear way to trace it back. I'd just take your ads off the affected pages, and keep going, if you can.
If it's actually *CLICKING* on ads, then it's a different thing than what I've had.
