Along these lines I don't have a Facebook, have tracker blockers, and other stuff. Spotify used to give me the strangest ads. I'd get some for super cuts. Then an ad about hair loss (I'm under 30 and my dad still doesn't have gray hair). Then ads in Spanish from Jared's (not even dating anyone. Plus these seemed to be targeted at women). Also I'd get TONs of ads for Spotify premium. Those were literally all the ads I got. (stopped using Spotify because after I started paying, maybe those ads worked, their Linux app broke and they said they didn't care about fixing it)
