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?
Mmm not sure how it will be managed. It depends whom you trust.
On our jlai.lu chat (https://jlailu.zulipchat.com/) we have a section that has a list of keyword to remove all post related to MAGA and far right. It gives us a peace of mind and we can purpose our keywords.
Imho, you may suggest a git, put your blocklist and invit some people to edit it. Honnestly, i think it is safer to handle personnaly because you know what’s inside. But i may be wrong
