Over the past decade or so have tried out Match.com, Date.com, Lava, eHarmony, POF and many others I can't recall, and have never met or messaged with anyone off of them...of course I would be aiming for the worst market....20s and very early 30s. I found that a lot of the different paid and free dating sites had a lot of the same women and like someone said, when I'd leave a site and go back to it after a couple of months or years it seemed like a lot of the same women were still on there. In fact, on POF I taunted a girl who I'd seen on Lava many, many years earlier (who I had messaged with no response)...I received no reply but when I tried logging in the day after or so my profile was deleted.
I tried putting up a fake profile with pics of Mario Ermito, unlike my regular profile which would receive barely a handful of views over a long period of time and no messages or responses, Within the first 2 or 3 days I received so many views and a few unsolicited messages right off the bat.
Edit: Also, I didn't target Indian women, but A LOT of pictures used in Indian female profiles are fake (Tineye was useless for finding fakes compared to Google).
