The fun of using AdSense or any other ad network. Surprise, Google doesn’t actually vet its ads.
This is why blocking adblockers isn’t safe, Google still can’t guarantee its ads are safe. At the same time, the site doesn’t earn without doing this. Tough spot to be in. This is why so few private sites are left, Google and the rest ran em out of town by controlling the money flow, or buying em up. Valnet didn’t go on a buying spree of the remaining private tech sites for shits and giggles.
