take a selfie holding a piece of paper with your name and the date on it is usually what people do. Because money is involved a lot of people make fake accounts pretending to be other people to get upvotes.
You don't have to do it, I myself have no validation but im also not trying to put up videos trying to say im in it. If u do a validation pict it will remove all the people saying your not really the chick in the video atleast.
