I try not to wade into discourse, but I feel like every time I see potentially urgent need for people to migrate instances on short notice, I wish Mastodon had true account portability with post migration. I think it’s beyond time to get it done.

@misty Someone on here said the issue is bandwidth: smaller instances might struggle with folks suddenly uploading several thousand posts including lots of media.

But not disagreeing with you. Most users (me included!) don't want to have to start from scratch and manually repost all their carefully-researched posts and threads. They want a preserved online history.

Others prefer to be ephemeral and even set posts to self-destruct, but they're in a pretty small minority.

@ApostateEnglishman The thing is, if instances don’t want to accept post history, they should be given the choice not to. But that shouldn’t block the choice being offered to others! I run this instance and I don’t like the suggestion I should be denied the chance to allow users to import their post history because some instances don’t want that.
