And I see those ads with uBlock Origin installed, congratulations, you're doing it right! I've seen this on one other site in probably the past 10 years. I think it was a custom furniture site I couldn't afford anything on but I was so surprised to see ads and that they weren't tracking me, I emailed just to cheer them on.

Yep hosting your own ads is the way to go. This way you are actually in control of your own content instead of relying on Google.
