Let me see:

It's a combination of:

-Misandry (Bitching about men)

-Harrasment (Constantly harrasing male users on that sub)

-Spamming (There was an article called "As Women Take Over a Male-Dominated Field, the Pay Drops" and it had different responses. For example, here and here)

-Hypocrisy (It said, no misandry is allowed and that is supports the rights of all genders yet when men's issues is discussed, they get defensive)
