I have been on and off that site for years. After a spending a good chunk of money fending off bots and a TON of scammers you might meet a real woman. If you don't mind going through the many rejections when women don't like your profile picture, think your too short, not their type, etc., then you might meet a woman who wants to meet. I have had a tryst and a long term affair on AM. The women were very nice and my long term thing was special, but I could have pulled that woman at a coffee shop or bar if the opportunity presented itself. If you're looking to have an affair, meet a woman offline. It's safer and less expensive. If you're looking for a hook up, or sugar baby then Tinder or OK Cupid is a lot more bang for your buck than AM.
Ps… there are a lot of lonely woman on AM who just want to talk and suck up your time. They make excuses for not wanting to meet. If you are not looking for something physical and are ok with the "online" affair, then it might be worth your time. For me, I wanted a physical thing and finding that took time, game, and money for those bloody credits.
