it's particularly baffling because mastodon has a decent account migration feature, i don't think it necessarily migrates posts but if i understand activitypub correctly you sorta get that just by saying "@this@account.com has moved to @that@account.net"
I was able to migrate everything else, so I'm guessing it's up to the instance host to provide that data. I managed to export a .json of all my subscriptions, profile info, etc... so I guess it's just a structural issue with how images and posts are shared.
Can't complain about lemm.ee as a service though, they've been upfront about the whole thing.
Yup, I was looking from afar for a few months back when I chose instance and lemm.ee was pretty much my second choice. Sad but understandable to see it go.
