No, I'd never seen their handle before, I don't think. Just making sure you knew anything you were addressing to them needed to be in a reply to them directly if you wanted it to land in their email.

Speaking of proofreading, the canonical spelling of 'Adrien' is A D R I E N. I have noticed you often end it with A N instead, as you did in the tags here, which I am betting is because your screenreader pronounces 'Adrien' and 'Adrian' identically without noticing the difference in spelling?
