Listen up you have added girl frauds to your friends list, they are frauds not really girls at all.
They plays many different videos on there cams to try and get girls to do things for them. Its not live its a video.
You can test them really easy.Just ask them to stick out there tongue or pull on there ear, something very random.
The video on there cam will not do that. You should remove them from your friends list and ban them if they come to your chat.
They uses screen recorder software to make a video of what you do on cam. They are also known to blackmail girls.
