Hackers have pilfered and published the personal details and sexual preferences of 3.9 million users of hookup website Adult Friend Finder.
Lusty lonely hearts, including those who asked for their account to be deleted, have been left in an awkward position after hackers broke into systems before uploading the details to the dark web.
Email addresses, usernames, postcodes, dates of birth and IP addresses of 3.9 million members have been exposed.
The UK's Channel 4 News, which came across the leak during a wider investigation into the dark web, broke the story of the Friend Finder breach on Thursday.
Rob Norris, Fujitsu director of enterprise and cyber-security in UK and Ireland, noted that the breach was the latest in a long line of similar spills.
