There is a tool to help migrate communities from one account to another to use when moving yourself to another instance called lemmy-community-copy.

It’s not a far stretch to imagine that something like it could also extract and package a user’s communities to share with others.

USENET was a mess too, though… The entire Alt.* hierarchy was an attempt to route around censorship and I’m pretty sure I recall lots of duplication of groups. /derail
