Mine are all super specific to sites I use and various elements of them I hate.
Just little things that I don’t want to see. “Score” gets blocked on Reddit. Don’t have a problem with the voting, but the numbers are just distracting to me.
For a similar example, I tend to go out of my way to create filters that block random visual ratings for media. Like when you search for a movie and get the IMDb or Rotten Tomatoes scores without having asked for them.
Not that I have a problem with ratings in general, it’s that they’re effectively opinions, and when I want to hear opinions on media, I’ll go look for them. I really don’t like looking up something about a show or movie I enjoy and see a giant visual indicator “HEY PEOPLE HATE THIS”, or vise versa. Or you’re just going to OpenSubtitles or a meta data site to get something and have to be reminded how the internet feels about this thing.
One odd stand out is Sonarr/Radarr. I can’t create a filter for those search results, because they’re not elements on the page apparently, and there’s no setting to turn it off.
