There's still a lot about that that I never said
Everyone is a crazy asshole
Anyway... Does this guy not know that when you legally change your name there's a record of it and nothing is really buried? Just because the feds have a harder time putting connections together when it comes to that, doesn't mean everyone else does.
When you change your name during marriage it's a different process, but there's still paperwork.
It's not buried, it's slightly obscured.
