Hackers have stolen data from a website where users discuss highly personal and explicit sex topics, including fetishes and trying to meetup with other members. The data is now being traded among low level hackers and data collectors, judging by posts on a cybercrime forum.

Although it’s not clear how many of the users on the hacked forum are genuine rather than fake or bot accounts designed to mislead members as some dating and sex sites have previously done, the news shows how the anonymity of users on particularly sensitive websites can be broken.

The site, called Flirtsexchat, includes threads such as “Public Sex,” “Baby Oil for Masturbation,” “Spanking Forum,” and “Do Girls Like Rim Jobs.” Here, users traded advice and tips on the various topics. In some threads users also advertised their social media handles.
