Never thought of the old cache possibility. I just know from being scammed on so many traffic purchases over the years, nothing would surprise me....even a dead campaign still sending in clicks months later.
I have purchased ads on sites where my ad never even showed up and was receiving hundreds of clicks from an ad that was never displayed.
The Cache explanation seems like it has merit, however the amount of clicks coming in are equivalent to when the ad was live.... that raises suspicion...anyways thanks for the input
