I own SOME of my accounts. I self host lemmy, email, and a friendica instance.
Sorry to bring it up yet again, but I wonder how this works on Bluesky. On Bluesky, I host my own PDS and use my own domain as my handle. I don't see how bsky could try to claim any ownership of either.
I recommend we use that random one I posted which is sure to be assigned to someone.
