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?
