I've tried and you can chat with genuine girls. Yes girls are paid a little (see AshleyPhenix's post above).
But, how do I keep in touch with someone on Luckycruh?
It seems to be impossible to find the person with whom you have chatted in a previous session. On the Coomeet site, which is also a chatroulette at first, it is possible to manage a list of friends and to call them if they are online. There is also a history of your previous messages. Nothing like that on Luckycrush! or am I wrong?

I enjoy chatting all the time, the most thing is not real but that's not important for me and im using lucky crush for now.

I want to figure out a solution or hack to get free minutes on lucky crush as i hate paying so much....
