Need help with students who've turned my class into a dating service

This feels like a fictional account, but I enjoyed it nonetheless.

Bill Gates and Paul Allen were doing something similar decades ago. According to https://www.bbc.com/news/magazine-35442969 (but well known before that):

> Paul Allen, who would later become a co-founder of Microsoft, was a couple of years above Gates at school. Together they fixed the school scheduling software to ensure Gates was the only boy in classes of girls.

For many people, college itself is a dating service.

Don't let senior level students audit junior level classes? Why are they even there besides the reasons outlined in the problem? This is a problem with the University because they don't want to acknowledge a problem. Do they really think that's going to last? If it was my daughter who left the class because she was harassed I'd be very angry.

Yeah but the girls in the 100 level course are required to be in that course to graduate almost for sure.
