The site does not trick you. It only tells you "JOIN FOR FREE" not "Use the whole functionality of the site for free". They offer a service and want to get paid. Totally legit.

Yes, it's free to put your name in. That's about it. That's not what they want. They want your credit card information. READ THEIR TERMS OF SERVICE. They own other sites that they can also connect you with and without your consent or knowledge start charging your credit card for. These sites all do the same thing. I was being charged for 3 different sites before I could stop them. Had to cancel my credit card. They're not even from the US. They're somewhere in England. Sorry.
