If you read the blog posts of at least one of the women it's very clear that in her story sex was involved. And I doubt he's contesting that part of the story.

Point I was trying to make is it's not actually that hard to be outside of the risk zone for being cancelled.

If you're mentoring a young woman, don't suggest to share Airbnb together, don't drink alone and then initiate sex. Not doing those things makes it extremely unlikely to ever be accused of taking advantage of someone.
