In theory you are right. However, I received a request from a 16-year-old, travelling with another 16-year-old and no one older. He had his own account.
I am not sure how this happened as I don't think he had tried to do something clever to by-pass the system because he was totally honest about their ages in his initial email. I just told him I don't accept under 18s and that was the end of it, but it did leave me wondering how this was even possible with 'verified' ID.
