If you use xHamster's tool to create or link an account on another platform, the two accounts now stay connected for features like messaging. Messages you send or receive — plus the username attached to them and other message details — can be displayed on that other site for people there to read. On an adult site, private conversations showing up under your username somewhere else can be a serious privacy problem, and once something is displayed on another company's platform, xHamster no longer controls who sees it or how long it stays up.
“the operation of linked account features across those platforms, including messaging functionality, with the result that personal messages sent or received through your account, together with the associated usernames and message details, may be displayed on the third-party platform(s) and viewed there”
What you can do — Do not use xHamster's tool to create or link accounts on other platforms if you want your messages kept private. If you already linked an account, check the list of third parties at https://xhamster.desi/info/list-of-processors, unlink where you can, and avoid sending anything through a linked account that you would not want shown publicly under your username.
