I have used DA off and on for the last 12 years of so, there are real women on this site and I have chatted with several. I will say it was better early on then it is now there doesn't seem to be as many women as there used to be, but it is not a bot patrolled scam.
There are real women, you don't have to pay to wink or send an opening line and they can respond accordingly. My system is to connect that way, then pay which allows emailing.
There may not be women in your area, sometimes requires assessing and then coming back.
