These look like standard disqus ads. Which is to say - like you see when you scroll to the bottom of a Breitbart article.

I would totally agree that this makes your site look like an armpit of the internet, but also - there was a way to figure out that this would happen ahead of time. Google Ads last I checked weren't nearly as bad, but even these were prone to scams and malvertising campaigns on sites I've frequented.
