Can you steal a user's identity if you gain their old domain name? (lemmy.world)

Just a random thought experiment. Let's say I have my account on a lemmy instance: userA@mylemmy.com. One day I decide to stop paying for the domain and move to userA@mynewlemmy.com, and someone else gains it and also starts up a lemmy instance.

If they make their own userA@mylemmy.com, how do federated instances distinguish who's who?

Have I misunderstood the role of domain names in this?

All valid arguments, code needs to be checked abou what is possible to implement. Even if we start with one way of dealing with those instances, it will be possible to chamge in the future.

Thank you for good discussion in this thread.
