Site says if you buy premium membership ($20) you will become a premium member for life. This is a LIE!! If you do not keep buying and spending tokens on the girls, the site will change your password and lock you out and send you an email saying you must pay another $20 to return to premium status. The site owner, Leo Radvinsky, is a crook and possibly involved with organized crime. Don't pay these thieves a dime! They will screw you over just like their webcam wenches do.
The site is indeed free. Sure, tipping (by way of the site's token system) is encouraged and will give you more but without spending a penny you can click around many cams and see quite a few models who are topless or fully nude, playing with themselves or even playing with toys.
Certainly their concept of what "free" means is more true than most regular porn sites where the only live models you can interact with for free will remain fully clothed until you pony up.
