Right but the instance I’m on could get taken over by an asshole, and get defederated by, or defederates from, my favourite subs. Then I’ve got to abandon that account and start a whole new one, same as I did leaving Reddit. I’m really not sold on this model until I can transfer my account somehow.
I believe Mastodon has a “transfer accounts” feature. I don’t know if Lemmy and Kbin do though.
It’s tricky to implement though. Unfortunately ActivityPub didn’t really consider account transfers as part of the initial protocol design.
It’s something Bluesky is doing better, since they designed their system to be able to handle transfers from day 1, as a core part of the protocol. (it’s going to become federated, eventually, but using their own protocol instead of ActivityPub).
