I discovered recently that eventually they catch you through persistence. Like YouTube ads, I was busy in another window and couldn't skip the add without interrupting something I was doing which couldn't be interrupted. So I wound up inadvertently listening to the ad, and they said some interesting stuff that make me pan back to the ad and watch it. Eventually ads catch you at an inopportune time, which is inopportune for you, but opportune for them.
