I think she has a historian background, although not sure if that’s what she works in nowadays - she describes herself as a historian on her Threads profile. Pretty sure she’s mentioned that she went to Princeton, also. I don’t know if she has used other names on older gymternet sites as I’ve only really been aware of her participation on Reddit (having spoken in messages with a handful of the people she’s chased off), although I know her Twitter ID too. I, perhaps foolishly (?), presumed her Twitter handle was her actual name.
Most of Reddit is ban-happy and expects people to stick to a preferred narrative. That’s why I end up going back to lurking after every attempt at commenting somewhere - you can even be banned from some groups just for being a member of another subreddit. It’s a shame as I think there are some gym fans on there who would like it to be more open to free discussion.
