How about a chatroom where non-friended users have to ask for permission to view another users cam? Moderators excepted. It would possibly increase the number of women being brave enough to go on cam, knowing that only people they have trusted to friend will view them and perhaps stop unwanted loathsome comments flowing through in pm's.If a non friend requests to view your cam and you do not wish them to, it would be as simple as clicking an ignore button on their request and they can go away, it could also block them from sending pm's.Just a thought.
Like the old Yahoo chat rooms were, a user could turn on their cam and it would show that user had a cam on, but if another user tried to view the cam it would ask permission from the first user, who could approve, deny, or ignore the requester.
