Ive emailed google about a week ago asking this question, but havnt received a reply yet. Ive been getting $1-2 daily from these clicks and its not saying where they are coming from. (all my ads have channels)
Sell a site with your adsense code intact recently? Happened to me and I was seeing clicks from nowhere. I now use the "Allowed Sites" feature.
yes, that's possibly what happened. good for you if that's the case..the new owner of the site won't find it..LOL
You want to know where all clicks are coming from so you are wrongfully banned due to someone abusing the code in the future.
