This particular dating network owns a bunch of different sites (NFMature.com, Bang Experts.com, Loveaholics.com, Naughty Date.com, Wild Meets.com) that we have reviewed in the past and have exposed for scamming people.
They use these type of fake winks to trick men into upgrading so they can communicate back to the women sending the winks.
Once you see it's an attractive looking local girl most men will be inclined to send them a message at which time you are prompted to upgrade to send any email communications to other members of the site.
Unfortunately most people don't realize that these profile views are completely automated.
Their profiles have been created to trick male members into believing that the site is full of hot looking girls when it's actually not.
You might be asking yourself why would a dating site go to the trouble of fabricating fake profiles.
