@0x0 so all the posts are "hard coded" with the path of the username that posted it, so designing a mechanism that would let a user move to another server and bring their old posts with them is sort of impossible with most fedi software. There are solutions to this issue in places like 'streams' nomadic identity and other places like Nostr and maybe Bluesky (tho thats yet to be seen in practice) but this is a space where the fedi really needs to do some work...
