What is a "scam dating site"? A site where AI-driven profiles you contact with, phish or socially-engineer your money out of you? That probably couldn't happen in 2015 let alone 2010, AI tech wasn't yet there.
If you mean just a "dating site where all female profiles are fake, generated by site itself", then well, it's just called a "dating site".
Whole dating sites industry - with hundreds if not thousands of companies, downstream industries providing them traffic, payments, and services of all kinds, industry associations, conferences, rich networking and whatnot - is doing just that. Always did. The few "real" dating apps/sites like Tinder are just a tip of the iceberg - no one tries to really imitate them - it's not possible.
Almost everything viable on the Internet today, is a "scam" in this (to my taste, extremely strict and old-fashioned, definition). Just because all available real attention has already been harvested a long time ago, and cost of traffic, which is extremely high now because extensive way of attracting it - by having people spend more time at the screen - is no longer available as people already spend glued to the screens all day - so every time to have them visit your site you have to pay more than the other guy pays to have them visit theirs - it's an auction and prices are through the roof.
Thus, if you sell people something which isn't fake, you aren't going to turn a profit. So all who did, are out of business - with the exception of yes, "big tech" monopolies that can exploit the shit out of people in a way no run of the mill scammer like those two poor hapless chaps can even dream of.
