In a weak moment I ignored my good sense and signed myself up to be done over by Ashley Madison. I probably deserved it. Please learn from my experience.
Most of the profiles are fakes or prostitutes and scammers. I got many messages from Russian scammers and prostitutes at clock work intervals (every 15 minutes or so on average when online). It would be easy to blow your credit messaging these people if you didn't recognise them. The few real women listed are unresponsive because they are already inundated with messages from the many men who make up the vast majority of users.
When I realised with considerable self disgust what I had fallen for I decided to close my account. Ashley Madison added insult to injury by gouging an exit fee just to close my account! They extorted extra money from me to "remove all traces" of my activities. Of course I'll just have to take them at their word that they did so. It felt like blackmail and just a little bit rapey too. You got me once Ashley Madison but what you bought from me is a lot of bad press.
With competition from Tinder and the like this business is circling the drain anyway and most deservedly so.
