I am not massively fussy about ads, and they don't bother me massively. But I am going to explode if I see the one with the irksome and sickly bloody Joe Wicks on it one more time! (Advertising some crappy kids thing.) His face sets me on edge. I can't STAND him! 
I have clicked 'stop showing this ad' and it says 'we will try not to show it again' and 2 minutes later, it comes up again. ARGH!!!
