Gregory's Server@rysiek Right now, with all the talk going on in this thread, it is making me afraid I may soon be forced to switch Mastodon Instances over some #cryptospam that was going on, and I have been on mastodon.social for around a year. Even though I could move the list of who I'm following along with my small mute and block lists over to another instance, I currently have over $1,400+ posts that aren't able to move.
@ShingoMouse@mastodon.social Calckey lets* you import posts that you've exported from your Mastodon account.
*it seems to still be work in progress, and not every instance allows you to do that. I've tried calckey.world, calckey.pl and calckey.social, and so far only the last one has got that setting enabled, probably because it can be a bit resource intensive.
