I don’t know if it’s been posted here before - it probably has - but Bluesky has a crowd-sourced moderation labeler called Aegis: @aegis.blue . It’s super nice. Normally I have some difficulty picking out if my follows are responding in good faith to a misguided soul, or are snarking at trolls. Finding the post they’re responding to covered in labels makes it abundantly clear that the person in question is an asshat.
