Most ads I see on YouTube are very dubious and poorly made. A reasonable ammount are plain fraud. It is very frustrating going to "ad center" and reading about how the advertiser did not verify his identity.

I wouldn’t be surprised if there was some kind of “annoyance” metric for the ad selection algorithm. The idea being: show a certain demographic the same annoying ad again and again, and they might end up paying just to get rid of ads. I’m pretty sure Spotify does this.
