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.
I’m actually flattered that I have this… reputation on Lemmy lol.
Personally, I don’t care if celebrities come and join, even Taylor. Honestly that’s one of the reasons I’m okay with threads starting to federate, I see celebrities joining there and then we can sub from our instances. Best of both worlds imo.
