I agree with you. Every dating site I've been on feels like a scam that is full of fake accounts and wants to charge you more money per interaction.
I had a lot of dating success with AOL back in the day. I had several longer relationships, quite a few short term relationships, and of course some duds with women I met on their. Part of what worked in my opinion is it was free since you were already paying for AOL and there were lots of people just hanging out and maybe interested in chatting/dating.
Earlier on when everyone was playing Farmville etc, they should have made a way to easily meet and friend/date new people without it appearing as part of your main activity on the site. Maybe they struggle with some of the same issues Craigslist struggled with as a dating platform.
