This is very, very unlikely, isn't it?
If a woman is sufficiently fed up to take a photograph and share it, it will be because the person in front of her is blatantly, obviously a man as many, many of the intruders into women's spaces are and quite likely doing one of the lovely antisocial demonstrations such as peeing or wanking with the door open, taking selfies or waving swords, and performatively being A Man Using The Women's Space.
I'm very much behind embarrassing the fuck out of those men. And I'm not up for them getting to hide, yet again, behind a lot of female socialisation about ooh but wouldn't it be awful if possibly, somehow, as a one off awful mistake, a woman got mistakenly accused.
I'm more worried about the women who will definitely suffer by letting these men crack on unembarrassed, unchallenged and enabled.
