I have a good friend who was harassed in-person in a very damaging way due to their non-pseudonymous work as a Wikipedia admin. Knowing their story, I'm surprised any admins would not be pseudonymous.
Wow. Sorry to hear that. If your good friend is a she then she should get in touch with "Jennsaurus" at Wikipediasucks.co ASAP because Jennsaurus is a journalist who has discovered and compiled two dozen cases of sexual harassment against women editors.
