Novice so please correct me if I’m wrong, but my understanding is you can still see and post on these other instances/communities. Local will still pull from your instance, but All pulls from everything (or at least what’s still federated). Definitely a need to block all the furry biz that otherwise populates on All/New but after some curating (and eye bleaching) should be good to go!

Check back up on it though. Saw a video where someone nuked account/comments and reddit un-deleted everything. Even if misleading, wouldn’t hurt to confirm account is dead in a bit.
