As much as I'm NOT here to stick up for Nic and his site, he is telling the truth that this is a 3rd party service. http://www.intellichat.com/demo is one of a number of services like that.

You put a tiny fake-ai-chatbot on the page to help with conversions.

Here in Toronto, I interviewed once with a dating site similar dating site similar to WooMee /* on second thought I won't link to them */ who "Seem" to be doing similar things (this is of course only alleged misconduct, as I have no proof)

There are also numerous accounts of the dating scam sites out there. I read one story of a "Sugar Daddies Dating" site that charged huge fees to sign up, then when you did a chargeback, they'd refer you to collections for many times what you originally pledged.

So it's either pay up or damage your credit rating. http://maxkle.in/how-elite-dating-sites-scam-people/ Max Klein has a good account of one such scam.
