That's exactly what I do when something manages to slip past my blocker. I also mute my TV and pick up my phone when ads start playing.

I don't generally hate the brands though. I understand there are some perverse incentives at work in the market which means they have to spend money on advertising or be outcompeted by others who do. I blame the advertising industry itself. There's one exception though: where I live, some businesses are so obnoxious they pay people to drive around playing loud advertisements all over the city and in my neighborhood. Those certainly get my utmost hate. I'd blacklist them forever but I can't even understand what the ads are saying anyway.
