Doxxing
Publishing personal information about someone online — real name, address, phone number, workplace — without their consent. Common harassment tactic. Term from "docs" (documents). Illegal in many jurisdictions.
Classic combo: 4chan mob doxxes someone → swatting (fake 911 call → SWAT team to the address). Gamergate (2014) established the pattern. Reverse image search + LinkedIn + property records + social-media cross-reference make doxxing research easy. Platform policies: Twitter/X bans doxxing (but inconsistently enforced — ElonJet account ban 2022 set example). Defense: separate "alias" accounts, password-manager-randomized usernames, don't share location data publicly. The brigading mob is often more harm than the original target themselves.
