What's to prevent someone from hijacking my username? (lemmy.world)

Since usernames are only unique to the instance it's created on, what's to stop someone from creating a copycat username in order to impersonate another user?

I mean depending on how you look at it. Usernames are really your name + instance, and that is unique. To know you are actually talking to the right person you just have to make sure that matches up

The username is structured as username@instanceurl so they will know it's you based on the instance url
