Because let’s say you’re Tom Hanks. And you get TomHanks@Lemmy.World
Well, what’s stopping someone else from adopting TomHanks@Lemm.ee?
And some platforms minimize the text size of platform, or hide it entirely. So you just might see TomHanks, and think it’s him. But it’s actually a 7 year old Chinese boy with a broken leg in Arizona.
Because anyone can grab the same name, on a different platform.
Taylor Swift’s Twitter handle is @taylorswift13 and it doesn’t seem to be a problem for her.
Because there can only be one taylorswift13.
There aren’t multiple instances on twitter.
My point is there could be a @taylorswift but it doesn’t matter because people know which account is hers.
