Interesting. They supposedly shared content previously that indicated they were not a woman:

Maybe, maybe not. What is the proof of the connection? Just the time of disappearance and the username? That is pretty circumstantial, but maybe. Not conclusive though.

EDIT: This article seems to have more evidence and is at least interesting: https://www.inputmag.com/culture/is-ghislaine-maxwell-secret... I think there is definitely a chance it is her. Strange.
