I'm having the same problem but not on youtube, I used to be able to use websites like porno.com.pt or porngif.co using adblock but now it wont let me in with it enabled. The only one that still works for me is gifsdesexo.com which is weird cause its built on the exact same way than the other one.
**EDIT * let me add that two of those websites are exacly the same but in a different language, one works and the other doesnt
Can't you guys patch this feature? It's annoying to see so much ads
