As stated in the title, there's a subreddit that bans men if they post or comment on posts. The mods go into your history to 'discern' your gender.

I can understand the rationale behind this but wouldn't banning users by the subject of the posts/comments, and not gender, be the right thing to do?

Is this even allowed under Reddit's rules of conduct?
