Hey, one way to do that is, to block the community in question, which you can do by going directly to the community and blocking it or go to settings -> block and adding the community to the block lists there.

For this community in particular, just block the bot that posts the capybara content.

There other Lemmy clients that let you use keyword filters to block content but I don’t know which sadly - see the mega threads on !lemmyapps@lemmy.world for a break down in Lemmy clients and features.
