Nothing. I'd never go without an ad blocker.
But don't you know those websites where you want to read an article, so you click past the cookie banner, but after a few seconds another popup goes up: "subscribe to our newsletter!!", and you click past that, just to see yet another popup that asks you to donate to buy-me-a-coffee or patreon, and at that point you've lost any interest in the article?
