Zoosk, Badoo and other social dating sites

Zoosk and Badoo seem to be the only alive social dating sites, but they are only for casual dating, for instant gratification; not for serious dating. They are using dishonest tactics to attract prospective paid members.

Other social dating sites closed and wasted tons of money because social discovering / social dating is illusory/vaporware.
People do not pay for social discovering, for finding new friends, they will pay only for high effective compatibility matching.

Behavioural matching from social dating is a complete waste of time, because behavioural matching can not outperform personality matching methods.  Now in 2013 I think C-Level executives from the Online Dating Industry do not want to innovate and offer a high effective/efficiency compatibility matching algorithm, because they are like burglars who are stealing the money of the daters, they scam daters with automatic rebilling trickery.
