Only 1 person I’ve ever tagged, who posts content I’m not interested in seeing, but I don’t feel like they deserved a straight-up block since they’re still active in discussions elsewhere. My app allows me to filter them without blocking them so I don’t see their posts but I still see their (default hidden) comments that I can open, so I just have a tag to remind me why.
Recurring trolls I just block, so I don’t even see them to necessitate tags to begin with.
I still use Sync because I’m stubborn and too lazy to learn anything new.
