Actually I might know why that is, for a while now Furaffinity to Google's/other browser's eyes was a nonsecure website even though it's really not sketchy at all, pretty much Google at first didn't want to do anything with FA is what I am assuming. Lately though I started to notice that Furaffinity is now a secure website to many/all browsers including Google. Not only that but when I check my FA on my phone DuckDuckGo just started to inform me that it has blocked some sites from stalking me on here and that started a year or more ago.

Still not sure if I'm correct with that but from what I notice/told you in that long text of words that is what I think is causing these Google ads to be all over Furaffinity when your on here
