I’m not sure how many ads on different sites are sketchy. I don’t feel like finding out, that’s why I block it. There have been plenty of reasons that all sorts of illegal stuff gets inserted on well-meaning sites, so it seems like it’s inviting all sorts of trouble to automatically click stuff without consideration.
I used to use old phones (Nexus 6P, Galaxy Nexus, Moto X) as security cameras, stopped for exactly this reason. They all got really warm, even with the screen off, and I was uneasy about it. IIRC my Gnex removable battery started expanding a bit! That’s when I stopped using them for it.
