It will work itself out. There have been splits in the past. /r/Indianapacers became /r/pacers and /r/prowrestling became /r/squaredcircle.

The real issue is having the same username on multiple instances. It’s going to cause issues.

I honestly think during the sign up the registration to a server needs to be randomized to spread the load. That and allow the user counts to be global and not just to your instance and you then have user load balancing.

If we could also migrate our data between servers with a backup server option. When lemmy.world goes down, just switch to a different randomized backup server.
