I installed AsRep about a week ago, and of course, it's working way beyond well. So I was looking at my traffic for my one of my test campaigns, and found that I was getting almost all my clicks from, of all places, MySpace (whcih I think kinda sucks since MySpace users can't put Adsense ads on their OWN pages to make money, but Google can (and obviously does). Anyway, I KNOW that my particular niche is not MySpace friendly, and MySpace is the LAST place I want to see my ads. So I paused my campaign, put MySpace in my competitive ad filter, waited a day, did some copy tweaks, and started up the campaign again. I checked my asRep logs, and the MySpace clicks are still coming. Now, what's THAT all about?
I would check your account, there has to be a filter which allows you to filter out myspace or any other website for that matter. If all fails contact Google.
