In case anyone is wondering why we're talking about the email address: it's a way of directing discussion away from the offender's behavior and towards the establishment responsible for enforcing standards of conduct. It is a political maneuver to resist this establishment and is part of a broader backlash against codes of conduct and their enforcement.
Secondly, it is a form of harassment: it aims to create a narrative that invents reasons for the conduct officer to be fired.
Third, it's a socially acceptable reason to be outraged at a trans woman exerting her position of power to reprimand a cis man. Doesn't matter if the reprimand is justified, or if she earned that position of power, etc.
