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.
The fix for this is for the guilds and unions that represent these celebrities to spin up their own instances. The suffix of the username granting the legitimacy.
It would solve the issue for people who look into it. But what if I registered AstralPath@Lemmy.World? I could pretend to be you. And because most people won’t check, I’d get away with it until people caught on.
Now if you make your living off your public image, and I say horrible things, your career could take a hit. Even if nothing I said is true, and its proven it was never you.
People will just remember “Hey, remember that time AstralPath admitted to having sex with their grandmother?”
“No, that wasn’t actually them.”
“Are you sure? I remember reading about it in (insert tabloid here)”.
And suddenly you have a legit reason not to use a platform that easily ruins your career through no fault of your own.
People will ALWAYS attempt to troll online for the memes. Remember Boaty McBoatface?
