At the moment, I’m browsing via phone, and my browser does not have ad blocking software. The ad at the bottom says something like “A trick your auto insurance broker will never tell you!” The picture is of a woman, legs spread, getting what I assume is a gyno exam, or maybe just being rogered with a dildo by a guy wearing rubber gloves. I’m on Android, dammit, which doesn’t allow the taking of screenshots without root access, or I’d have proof. The ad has been replaced, but I’d bet a nickel it shows up again…
Sounds like a hack. Hopefully a one-off, but if it recurs save a screen shot if at all possible; a porn shot in an ad would definitely focus their attention in Mountain View.
Although that may be one of the more honest ads on the site, because, chances are, your insurance agent probably won’t tell you to get “rogered with a dildo by a guy wearing rubber gloves.”
I see plenty of the ads with that text, and I get the impression that whatever ad company it is just sticks randomly-selected pictures from the far reaches of the Internet onto those captions. I’ve never gotten a porn one, but the irrelevant ones are far more common than the relevant.
