We've become aware of an issue in X for Android that disabled the "Protect your posts" setting if certain account changes were made. You may have been impacted by this issue if you had protected posts turned on in your settings, used X for Android, and made certain changes to account settings such as changing the email address associated with your account between November 3, 2014, and January 14, 2019. People on iOS or the web were not impacted. We fixed the issue on January 14, and we'll provide updates if other important information becomes available.
We've informed people we know were affected by this issue and have turned "Protect your posts" back on for them if it was disabled. We are providing this broader notice through the X Help Center since we can’t confirm every account that may have been impacted. We encourage you to review your privacy settings to ensure that your “Protect your posts” setting reflects your preferences.
We recognize and appreciate the trust you place in us, and are committed to earning that trust every day. We’re very sorry this happened and we’re conducting a full review to help prevent this from happening again.
If you have any questions or concerns, you can contact X’s Data Protection Officer, Damien Kieran, by completing the online form located here.
