If you decide to sign up for a dating site, consider taking a few steps to make it harder for a dating site to easily identify you.
Whether you signed up on a lark or maintained an active profile for several years, your online dating profile can be lurking around long after you’ve cancelled the account.
The most pressing concern is that information about you may be exposed to future legal requests that might involve a criminal investigation, a divorce case, or even a legal tussle with an insurance company.
Photos in particular can linger long after you’ve deleted them or closed your account due to many large websites hosting user-uploaded photos with Content Delivery Networks.
But in Bonneau’s experiment with 16 popular websites, removing the photo from the main website didn't always remove it from the Content Delivery Network; in those cases, anyone who still had the destination URL would be able to view the photo.
This means that Content Delivery Networks can maintain caches of sensitive photos even after users “delete” them, leaving photos vulnerable to being rediscovered or even hacked in the future.
