I have a good feeling CPM ads are being displayed on my proxy site, instantunblock.com. I remember seeing a guide here awhile ago on catching CPM ads? What is the best way to get rid of CPM ads? There are a lot of sites appearing in my Adsense ads and I have no clue which ones are CPM ads. With my other websites, it's been very obvious which ads were CPMs (it was almost always a large company and an image ad was used).
