Worth considering that with the post in question, these male students are auditing the class so in general they have no consequences if they fail. They are there solely for the purpose of trying to sleep with younger female students and need to place no consideration on their academics.

And as for how pushy they are, according to the author, these male students are trying to take on a perception of authority (acting like instructors/TAs during classes) which implies some amount of attempted coercion (whether explicit or implicit) is likely taking place.

This type of power dynamic is really dangerous and it's a matter of time before somebody particularly scummy takes part and ends up victimizing one of the female students who are actually trying to pass the class.
