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?
You don’t seem to get my point. For a platform to let me reliably filter a whole topic, the majority of posts need to be tagged with that topic first. Reddit/Facebook don’t do that, they have communities and loose categories, not consistent topic tags across all posts. Twitter only partially does it with hashtags, and hashtags are neither comprehensive nor applied consistently. I’m talking about platform-level, booru-style or collaborative tagging so blocking a tag actually removes the tagged content without me having to unsubscribe from dozens of communities or build giant keyword lists.
Imo it might be easier to collaboratively build keyword lists. It’s tedious to tag posts manually, and it becomes impossible to do it effectively after the user base grows past a certain point. You can auto-remove any post that isn’t tagged, but a lot of people dislike that kind of filtering and only a few communities would implement something like that
