Somewhat related, there is a site I follow called royalroad. Royalroad is a site for web serials, which are basically books uploaded to the internet chapter by chapter.

Although royalroad used to be only google ads, at some point they started accepting user submitted ads. (Also, ads on that site have always been unobtrusive).

I like these ads much better because they are more privacy respecting (literally an a image and a link).

Also, they are really funny. User’s with no art skills will make memes, or doodle stick figures, and I clicked on that one anyways, and the story was soooo good.
