As details about Ashley Madison's business continue to spill forth through two massive data dumps by hackers, details have emerged of a document titled 'Management Presentation' which reveals revenue numbers, membership growth rates, and explains how it keeps 'undesirables' off the site.
Ashley Madison defines undesirables as prostitutes and pornography purveyors.
According to the document, part of how the company detects who's a prostitute is by looking for "over usage of the site." In case they accidentally ban someone who is just really excited to have an affair, chronic users are then marked for human review.
It says the company then collected the IP addresses of people it believed to be prostitutes, and dropped cookies on their computers that basically communicated: "This is a prostitute".
The site then used these cookies to redirect the suspected undesirables to a dummy site on which they had no possibility of making contact with Ashley Madison's other users.
Hackers, known as the Impact Team, stole data from the website last month. It included users' names, email and home addresses, and message history. The hackers threatened to reveal the information unless the site was taken down.
Ashley Madison is a Canada-based online dating service and social networking service marketed to people who are married or in a committed relationship.
The site says it operates in more than 50 countries and has 37 million users, more than a million of whom live in the UK. Its slogan is "Life is short. Have an affair."
