Seems like the Movetodon thing works WAY better than another one I tried a couple of weeks ago. Also seems that if you hit "follow all" on almost 450 accounts, Mastodon kinda freaks out.

Figuring out how to migrate to a different instance is a hell of a thing to do right after waking up at 4am. If I was following you or vise versa, then I wasn't and now I am again, that was probably me making a mess of an account migration. 😂
