I am 66 and posted no photo there, getting about 50 letters a day showing interest in me, 18 to 25 mostly as I indicated in my profile that is what I like. The letters seem to be computer generated, so are the chats, both are to collect a lot of money if you read or reply. The more expensive video chat may show you a real person at the other end but I am not going to spend $0.80 a minute trying that, knowing that many CAM girls in USA charge much less and entertain much more. There is every reason to suspect the person in Russia or Eastern Europe you pay $48 an hour to video chat is doing so for MONEY and every reason to believe $48/hr is much more than most make in that part of the world.
Also seen reviews from persons who use Joe Blow or WanURUS$ as their names and they do receive many letters of interest from girls there, indicating that the website automated chat or letter generator is not smart enough to distinguish a real name from a joke one.
