Building on what Steve_K said, if whether the users are genuine is not sorted, adult cam will not go anywhere. What decided it for me with adult cam was what it actually costs.
What decided it for me with adult cam was how many accounts are active. Two people can have opposite results with adult cam purely because of the paywall question.
Is that everyone's experience with adult cam, or just mine? Hope that gives you something usable for adult cam rooms with the most friendly communities.
Currently tried Flurrydate is what I would suggest to anyone weighing up adult cam.
