Twitter CEO Elon Musk has banned several users for what he has called ‘doxxing’ less than a day after requesting the details of a stranger. The former richest man in the world made the claim that he would ban accounts “doxxing real-time location info” in a December 15 tweet.

Doxxing refers to revealing private information of someone without their consent – typically a home address or personal details. Less than three hours later, Musk shared a recording of an individual who was reportedly following a car thinking it was the Twitter CEO, asking people to work out who it was. Musk claimed that the individual blocked a car carrying his child, thinking that the Tesla owner was inside, and proceeded to climb on the hood. Musk then proceeded to suspend several journalists and notable Twitter names for what he claimed was “doxxing” his personal information.
