Reminder that if you see a trans person's deadname (or really any person's name you don't already know them by) through indirect means because of all the places we have to use "legal names" or names slapped onto bank accounts: no you didn't.
I have had situations where I had to use PayPal or some other thing that had my legal name on it to send someone something, and in return I got the childish taunting "ooohh, I know your real name now" with a threat—or action—of calling me that over and over again to rub it in. That is outright bullying and makes me anxious to give mutual aid sometimes, which makes the world worse for everyone. Don't be that person.
