Ads showing on sites I don't own warning. How to find which one(s)?

[NickMNS]

In the past 7 days, your ad code has appeared a significant number of times on sites you don't own.

I am seeing the above message in my Adsense account. I have verified all my sites so I am not overly concerned but I would like to know which websites the ads are appearing on. If I recall from seeing this in the past the affected websites will usually appear in the sits report. By there are no sites showing that i don't own showing.

I suspect, but I am not sure that this may have something to do with me recent use of DFP. In AdSense, I can't find any reference to the activity reported in my DFP account/dashboard. I am wondering if I have misconfigured something (I have another thread on that topic and as far I can tell everything is okay). But this message makes me wonder.

So my questions is, is there a way to find the sites were my ad code appears?

Strange you don't see these sites under: Performance reports > My reports

[NickMNS]

Yes it is strange. I am glad that I am not the only that thinks so. This is why I am thinking it might have something to do with my DFP account/setup.

Either associated with the recent addition of DFP - or - another bug with Google's reporting.

Is there a hint of action against you by g for their current reporting? Otherwise, keep an eye on it, send trouble reports regarding their error notifications, and take a calming breath and do nothing ... if there is really nothing you can do.

Other possibility is scrapers have scraped not only your content, but your adsense codes as well. You would think g knows how to handle that ...

No, nothing.

This is what I would normally suspect but, I that case I would expect to see the offending website's domain name appear in my reports. Only my verified sites are showing up.

DFP is what I am guessing might be causing the problem, but I have checked and I don't see how or why, so I am having my doubts now.

Could this be a side affect of Cloudflare? I recently started using their service.

So I think I am finally getting to the bottom of this...

googlesyndication.com

Has began to appear in my Adsense "My Sites" report and is unverified. As far as I can tell this the result of adding AdSense via DFP.

Given that it is month end, I have verified the domain.
