Hey L33t, did you even bother sending an email to Google? it looks like since they didnt pay you for the clicks they already filtered them, but I would still be a bit nervous..
This happened to someone I know, the screenshot is not from my account. I guess he must've warned Google about it, I'm not sure though.
That must be someone using the ClickMonkeys.com service.... I cannot see how else 10M clicks can be generated. WOW.
