It appears as though someone is displaying my adsense code on a domain, racking up 10's of thousands of (fake) impressions to my account and hurting overall CTR, RPM and possibly QS. Despite my best efforts, there does not appear to be anything I can do about it. Domain owner is unresponsive, and Google allows this.
Here is what I mean about Google allowing this:
1) Even though you can have an allowed sites list, this does NOT prevent Google from showing your ads on sites you have not allowed.
2) It seems Google permits sites that are not on your allowed sites list to not only display ads from your account, but also count and attribute impressions generated from these sites to your account.
So the end result seems to be this example: For the day I see 10k impressions overall on my account, but if I run reports on the allowed sites the number of impressions is far less like 1k.
This doesn't seem right...Am I missing anything here?
I'd bop over to the AdSense help forum and see if I couldn't get the attention of some Google person. I've never seen a case where they continued to show ads after you blocked your code from displaying elsewhere, but they've certainly been shown to have bugs in the system, so I wouldn't rule it out.
Here is a snippet from the little "?" next to "Sites authorized to show ads" in the account: :-(
Site authorization is an optional feature that lets you authorize specific URLs to use your Google ad code. URLs that you don't include in the list of authorized sites will still show ads and report clicks and page views, but you won't generate earnings from them.
