Linkedin Online adult dating site AdultFriendFinder recently reported that they’ve been breached, and have sought the help of law enforcement and security specialists to investigate the incident. According to the report , the information of close to 4 million of its subscribers have been leaked on a darknet forum, exposing emails, usernames, dates of birth, ZIP codes. While data breaches have hit a number of different industries that include retail, medical, and educational sectors as well as government institutions, the sensitive nature of the data exposed in this breach presents a different type of risk for its subscribers.

Articles on data breach incidents, prevention, and best practices ] AdultFriendFinder is, after all, different from your normal social media, online dating, or profile sharing platform, and saying that it’s nothing like OkCupid—a service that promises “online dating and friendship”—is an understatement. AFF is pretty blunt about what it is and what it offers, with a site description that promises the potential to “Hookup, Find Sex, or Meet Someone New” for its subscribers. In this incident, the users whose information may have been leaked won’t just have to contend with the usual issues normally associated with a data breach spam, hacked accounts, identity theft and exposed credit card info.

The leaked information, which was listed in a number of spreadsheets, doesn’t just include personally identifiable information; it also lists some of the users’ more personal details, such as sexual preference, which users are open to having extramarital affairs, and which specific adult-oriented forums the user has been most active in. Unfortunately for affected users, this incident isn’t something that can be fixed with the cancellation of a credit card or a changed password.

The details that have already been leaked amount to something more than just about protecting an account. It’s about protecting private, personal details and a reputation. When personal details of this nature become public, this opens up the breach victims to blackmail and extortion—at the very least, they could expect situations that involve Internet shaming and awkward explanations.

Getting swamped with messages drives users, especially women, away. So we have to analyze and redirect this tendency, lest OkCupid become sausageparty. Every so often we run diagnostic plots like the one below, showing how many messages a sampling of 5, women, sorted by attractiveness, received over the last month.
