@hoarahloux She's taking advantage of drunk young men new to university. Obviously freshers week involves a lot of sex. I feel like an experienced older woman targeting clubbing 18 year olds, who will be drinking, is taking advantage. If this was a man, imagine what would be said.
The first point is that the men are unlikely to be drunk. This would be a planned activity with a camera setup during the day, not a random night time thing.
The second point is that, contrary to popular belief, university students do not have loads of sex, particularly young women. If university students were having sex and having relationships, then you wouldn't have a queue of thousands of men messaging this woman.
