Adsense impressions with no channel

Where do they come from?

[pompousjohn]

I seem to be getting adsense impressions from some source that is not one of my URL channels, and I am pretty sure that all the url's I have adsense on are accounted for.

Is there a way that I can find out where it is coming from?

Could somebody be page-jacking me?

If they are using your publisher code, wouldn't that be like breaking into a bank and depositing cash? Come to think of it, that's probably the explanation ("cache").

Ah yes, must be it, I have moved some URL's and done some site restructuring. It makes sense now.

As far as breaking into the bank and depositing cash, I think most of us would be nervous about someone else using our adsense PID, just as any bank would surely press charges for a break-in, regardless of its purpose.
