Your comment blames the victim. Don't do this.
Whether it's a professional networking event or a fun, crazy, not-so-professional party, no one should be treated in this manner. No matter her (or his) behavior or the atmosphere. Period. Also, she mentioned "sitting on laps" because there was no room in the party, and people have a right to flirt without being, uh, sexually molested.
Finally, the linked article cites this as one example. There are many others, like when the author
organized a group outing to a pub, only to have one of the invited workshop attendees grab my ass while I was having a completely normal conversation.
(EDIT) sp332 points out that GP is discussing the environment at these events, but we're operating in shades of gray here.
The author talks about how the attitude towards women at these events is "institutionalized sexism." That is, people hired strippers etc. for years, and that attitude still exists at conferences/events. Noira could've been out-of-bounds by sitting in someone's lap, but we don't have any information on whether she knows the person, has a relationship with them, etc.
Still, GP's comment implies that Noira's behavior fosters the "sexualized environment" the author is complaining about. My point is that there's a big leap from Noira's flirting to women being groped.
