@rysiek Not sure if I mentioned it but I'm building a tool people can use to move their content to new instances (since Mastodon only migrates follows). I felt a bit "held hostage" when my content focused account ran into problems with instance admin and I realised how tough it'd be to move. Can only presume that's what they're talking about.
In any case, a test version should be out within a week or so. Testing it myself at the moment to migrate 140 posts with images and video.
@tokyo_0 ah that's interesting! Thanks!
