When a report is made, Chaturbate has a team of people that check the ID for validity, watch the cam(s) of the person in question and they look at still photos associated with that user name. Then a group decision is made on whether the broadcaster "looks too young" according to the laws and details associated with the 18 USC section 2257 concerning adult performers (this includes images such as a woman wearing pigtails and playing with stuffed animals, if you can imagine....
) In some cases, the decision is that the broadcaster does appear to be too young, regardless of the ID stating otherwise.
Thank you for understanding!
