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 to use that feature extensively on Reddit (with RES) to great success and minimal effort.

However, I’m not a fan of centralized crowdsourced tagging. Topic tagging is significantly more subjective than e.g. the functionality provided by crowdsourced extensions like SponsorBlock and will likely significantly reduce/fragment engagement if shared blocklists become widely adopted. Imagine somebody tagging something inappropriately to soft-censor certain posts to groups of users… there are many scenarios that this could be misused if improperly designed or implemented.

There is an argument to made towards making flairs a thing on a post/community-level and allow blocking from that. It’d be neat to filter memes, for example.
