After reading all 14 pages and just being suckered in myself, here are a few things I noticed:

As stated before, there are plenty of female accounts "online" all the time. Given the nature of the website, I find this highly unlikely.

After readying all the posts here, I see a theme for younger women (20's) contacting older men (50's) If I was AM, the men in their 50's, from a disposable income aspect and aging marriage, would be my target male demographic. Coincidence? I'm skeptical.

Has anyone else noticed that of the female profiles with pictures, there is an odd similarity to the way the "marker scribble" covers parts of thier face? I also noticed the same shade of pink used quite a bit.

...awful lot of new female profiles popped up in my 20 mile radius after I joined but before I paid.

And I'm sorry, what exactly does AM stand to lose with their $250 guarantee? You hook up or they give you back the money...big deal for them. And isn't that in some way a form of prostitution where the pimp keeps all the money?
I certainly don't doubt a few people have had success, but I would bet my 401k its a REAL small piece of the pie chart when compared to crafted, fake female profiles and AM's "bag of tricks."
