Because let’s say you’re Tom Hanks. And you get [email protected]
Well, what’s stopping someone else from adopting [email protected]?
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.
If anything we want to encourage this.
I like the example of SAG AFTRA hosting their own instance to be official, for example. Celebs typically have their own domains and websites, so easy enough to hire a team to create and manage their own instance that supports the celeb but federates. And you know it’s legit just because it’s on the celeb’s own domain. Ditto for gov’t agencies having their own instances.
