Depends on the person. The point is, it's entirely up to you. And keep in mind you're not guaranteed to get the same name on every instance you create an account.
What premise? It's not a philosophy. It's an outright technical observation. You can do whatever you want. I didn't say you have to like it. What is there to disagree with? You can say the idea isn't for you, but it's still correct.
That's fucking stupid. I'm done here. Someone in the thread even already posted their two different account names. I guess you think that's just an illusion. Fucking idiot.
