Settings > Filters & Blocks > swipe to the left on whatever needs to be unblocked. Good luck!

Settings > Filters and Blocks. Swipe left on the keyword. Press unfilter.

Including the word fat-taco so that you may check if it worked.

Interesting. Didn't know this was a feature. How does the filter work? Completely hides comments/posts containing the keyword?

Or does it do something like Steam does by turning every letter into a ♥?

I tried to add the word "swipe" to the filter list, but I can still see the other 2 comments on this post along with the word "swipe".
