Doxxing

For anybody with an audience this is a live safety risk rather than a theoretical one. Details leak from ordinary places: a reflection in a window, a delivery label on a box, a school uniform, EXIF data on a photo, a domain registration nobody made private. Once out, it cannot be recalled. Prevention is most of the defence, so use a PO box or a registered office address on business paperwork, keep WHOIS privacy on any domain, and check the frame before publishing anything shot at home. If it happens, report it to the platform, preserve screenshots and involve the police, because in the UK it can fall under harassment and malicious communications law.
