How does this system handle unique usernames? It seems like a flaw in the system if other people can take unique-seeming usernames on other servers. Will this network be overrun with impersonators?
@mathowie I guess it's more like email addresses? There's a matt@gmail.com and a matt@hotmail.com
@mathowie on matrix.org if there is another person with the same username being federated then it shows the whole name
