“Cat looks inside”

https://knowyourmeme.com/memes/cat-looks-inside

Most mobile clients allow you to hide posts that contain a certain keyword in their title. Here’s a non-exhaustive list of clients that support keyword filtering off the top of my head:

• Voyager (multiplatform; I believe you need to have the app because the option doesn’t show up on the website for me)
• Mlem (iOS)
• Arctic (iOS)
• Thunder (Android)
• Sync (Android)

I don’t know of any that can hide posts with a keyword mentioned in any of the post’s comments; doing so would require the client to make a lot of extra API requests.
