>If you don't look at those posts (and even flag one as "not interested" when it pops up) they go away pretty quickly.

this is broken, I get stupid posts with same image, about body parts and english words for them, I marked it as not interested at least 3 times, but it appears again and again from other poster . So FB is incapable to now show me the exact same thing over and over again despite me telling them 3 times I am not interested.

Also I doing some math stuff with my son so now I am getting images with math in them, tracking really works
