My blood family consists of violent homophobes that would shoot my house up if they ever learned I'm gay (or where I live).
I have a dedicated online persona (fursona, really) that I keep compartmentalized from people I distruat.
Some of my friends are trans.
Some of my friends have abusive ex-partners and stalkers.
Some of my friends are sex workers who need social media to find customers but don't want their real names leaked.
How would your proposal serve any of these use cases? From where I stand, it'd be more of a hindrance.
