Adsense has bug up its ass about a very small image on my site of an old infamous album cover by Roxy Music that has two models in sheer underwear.

Five years ago (at least) they sent me a warning about it, and I removed all Adsense ads from the "offending" page and replaced them with Amazon ads.

Now years later I get a new warning about the same thing, even though Adsense ads have been long removed.

Is this worth pursuing, or would it be like arguing with a brick wall?

I'm wondering if it could be due to an old copy of my site someone has ripped off or something like that.
