I don't have a dog in this fight and I'm honestly not picking sides, but in reading this, a dumb legal question came to mind:
How libelous is "Raw Alex is ANYTHING" since Raw Alex isn't a legal entity? Contrary to popular belief, my birth name wasn't Peaches. I daresay, Diamond Jim's wasn't Diamond Jim (though I could be wrong

), MikeAI probably isn't really MikeAI, and I'm thinking Raw Alex isn't on anyone's birth certificate, driver's license, business records, tax certificates, etc.
I'm not asking to stir up trouble, I'm honestly curious as to where a "username" starts and stops being something you can legally defame.
