There should be a Fediverse platform that makes blocking entire topics as easy as blocking a tag, not subscribing/unsubscribing dozens of communities. Firefish (antennas) and PieFed let you follow/block keywords, but that’s not the same as robust, community-wide topic blocking. Imagine collaborative, booru-style tagging across posts so blocking a tag reliably removes all content using it. Does anyone know of software that already provides topic-level blocking out of the box without needing long manual lists?
Keyword blocking works on piefed. As long as people add image descriptions, it works well even on the meme communities.
