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?
Here’s hoping keyword blocking hits Lemmy/my instance is able to facilitate its planned switch to PieFed without a hitch in the future. I used that feature extensively on Reddit (with RES) to great success and with minimal effort.
However, I’m not a fan of crowdsourced tagging. Topic tagging is significantly more subjective than e.g. the functionality provided by crowdsourced extensions like SponsorBlock.
I feel that crowdsourced tagging will likely reduce/fragment engagement if shared blocklists become widely adopted. I can easily imagine somebody tagging something inappropriately to soft-censor certain posts to groups of users… there are many scenarios that this could be abused if improperly designed or implemented.
There is an argument to made towards making post/community-level flairs a thing and allowing blocking from that. There could also be basic/broad meta-level flairs (e.g. Photo, Video, Meme, Discussion, etc.) that could also be used to filter content.
