My guess is that most of them don't know how little free speech they have. Of the ones that do, they measure their words carefully, lest they say something the moderator disapproves of about the right to choose, trans issues, respectful gender critical ideas, empowerment in pornography/sex work, the existence of Muslim feminists, etc.

I did have an idea about using the Reddit API to produce a 'top posters' list from the affected subs, so interested individuals could PM those folks in a coordinated fashion to let them know of the moderation problems of AF, and to let them know of alternatives. However I am not sure if that would be against the terms of use - collecting usernames is probably OK, but organising a mass private mailing might be regarded as spam by the admins.

In any case, we don't have a lot of traffic here anyway - chicken and egg!
