I have now been using the Sits for second time, and it is my strong conviction is not genuine. I believe is run by an Administrator and the whole way of getting you and other suckers like myself, is to as loads of traffic to the site as the make loads of money on third parties publicity. Just be careful what you write on this site.
I will be continuing my research a bit further..

I search for a review of FDating because despite using the site over tie before, my profile is now fluctuating between active and 'temporarily unavailable and I have now idea really why. If there are multiple moderators it seems as if one has it in for me and the other(s) are activating the profile after I email. Else it's because I am accessing the profile using different browsers on my PC and Android phone. Although this seems unlikely.

I don't know about Greg's review though. I have meet a number of women on the site and continued corresponding even later for some time using mobile messengers.
I don't know how much credence to place in Greg's methodology because for example, many women on paid local site I also use often for example, and especially when new, leave the default out age details for a ideal partner. 18-99 are default values and simply means they overlooked changing them.
There are equal amounts of men who have not entered a personal description or ideal partner description. The site system then auto populates those fields as -n/a. Doesn't mean anything.
