If you are a man it's nearly impossible to meet a nice woman there! If you are a woman, no matter what you look like, you will get inundated with messages from all kinds of men.
For those men who don't want to get involved in this crazy and fierce battle for the woman, there is a better option:

It's time-saving and money-saving, and what matters most of all they have really awesome-looking, super-hot women, who are hungry for men. I had gone on dates with several girls, so it's all real and working.

As Sam said, if you are a woman you will be inundated with messages. It doesn't matter what you look like. But the site is probably 98 to 99% men, So for men it is far more difficult to impossible to find a decent woman depending upon your area and the fraud profile makeup in your area.

I became a gold member and once I put my pic up, I got overwhelmed with responses. I am no beauty queen either; I look like a sweet Sunday school teacher. Had to redo my profile and get very specific about what I wanted because too many people were inboxing me. Then, I got as much background info as possible on potential dates and did background screens. Canceled many dates due to men lying about age, marital status, employment, etc before finding a decent fellow. Many men wrote to tell me to be careful. Maybe they could tell how naive I was about online dating--who knows?!. Would recommend.

The odds of actually meeting new people from shooting them a message after looking at a profile are pretty slim. The best way to meet people on AFF is to look at local get togethers from "groups", in your area. They sometimes have regular meet and greets or activities at a local bar or club. This creates a safe environment with quite a few people attending. It also separates the fake profiles from the real ones. How you act at these meet and greets determines if anything will go further. If you're lucky, you might be invited to a house party.

I received over 300 message on adultfrinder, responded to at least 65%, then "poof they were gone... The reality of it is, to me, bull$#*!!

For me it did. I don't think it works for everyone. I think it helps if you're a woman for sure though.
