I think you're the first person I know who's ever claimed to have any success getting laid (or getting his cock sucked) on Ashley Madison.
Ashley Madison wasn't the only site using fake accounts to keep men enticed, though. I belonged to a couple other dating sites that used very obviously fake female profiles when I was trolling dating sites a few years ago. At least one of them wasn't using completely fake accounts; several of the "women" on the site were identified in their profiles as being employees of the site, and I immediately suspected that the only reason they were messaging me was to keep me interested in belonging to the site and to entice me to pay for a premium membership.
And for that matter, I've heard tell that eHarmony is a big site for men getting slammed with messages in their site inbox either before they pay for a "premium" membership, or about a week or less before their paid memberships are due to expire--the kicker being, of course, that you can't read messages unless you're a paid member in good standing. Needless to say, the "ladies" who are slamming your inbox then fall strangely silent after you pony up for a membership/renewal.
I only know about eHarmony second hand, though. I've never had the patience to actually join that site; it takes longer to fill out their damn questionnaire than most of my relationships have lasted.
Cheers,
