I think cringe is the wrong word. We cringe when we watch The Office and see people make social mistakes without meaning to. These are not unwitting social mistakes. This is people being assholes because they know they can get away with it.
Furthermore, not having met any of these people but speculating based on my experience, I would guess that their motivations go beyond just looking for sex and knowing that one time in twenty it will work. I think they also enjoy the nineteen out of twenty who are repulsed and insulted but don't -- correction, hopefully, didn't -- think they could afford to call them on their bullshit. Very few people are genuinely indifferent to putting someone through an experience like that, but it's very common for people to enjoy it. Those are the people we call bullies, whether their acts are criminal or not. I'm sure the people described in the article took care to stay on the right side of the law, but reading this I can't help hoping that they made mistakes.
