If there is no global username then that is a major flaw
@princessfluffy that's the price of federation in some sense, right?
@schlink No I don't agree. There needs to be clarity around users and their online name across instances
@princessfluffy I understand where you're coming from. If someone copped my name, photo, and bio on another instance and started imitating me I'm not sure how that'd play out; but as it stands I'd be at the mercy of the admin of their instance, which theoretically could be the imitating user.
