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.
It should work the same as email: you can trust it’s them if the user account is hosted on their own site, or their employer’s, or if they link to it from another confirmed source.
But look below in the comments. Can you even tell which of my comments came from Lemmy.World, and which comments didn’t? Some platforms will just show Lost_My_Mind. I can’t tell which platform @AbouBenAdhem is posting via. I just see AbouBenAdhem.
I’m not familiar with every client, but on mine it only hides the domain for users on my own server. (Early email used to work exactly the same—you could send an email addressed to just a username with no tld and it would go to the user with that name on your own server by default.)
I’m not using any client. I’m just using the browser that came with my cell phone.
Yes. Yes we can.
