On paper, the virtual kind, and, presumably, the physical kind on file in some legal office, Twitter bans doxing. In reality, it’s prevalent on the platform and, in this case, even trended as social justice mobs sought a white guy they’d seen in a video and settled for any white guy.

Weinberg hadn’t seen the viral story about the trail where he regularly biked. He didn’t know that, for several days, the video had circulated online as law enforcement crowdsourced help in locating the suspect. Now that he had seen it, he didn’t think he looked anything like this guy. And he didn’t understand why anyone thought he was him.

“You assaulted a little girl and other innocents because of your political beliefs,” one Twitter user messaged him. “Hey so are you the piece of shit who assaulted a child in Maryland today on the bicycle trail?” asked another. “Hey you racist bitch….we’re coming for you.” “You deserve to pay.” “Ur going down u disgusting piece of shit.” “Nice job assaulting a small child today. You need to be fired from your job immediately.” “YOU UGLY RACIST BITCH.”

His fiancée in New York, he spent the night alone, refreshing Twitter, watching helplessly as people tried to destroy his life. And Weinberg wasn’t even the only one: Another man, a former Maryland cop, was wrongly accused, too. The tweet accusing him was retweeted and liked more than half a million times.

The real question is why Twitter allowed and continues to allow this, even as it cracks down on conservatives. The answer is obvious. It’s for fighting racism and there’s no ban on doxing people when you’re fighting for a good cause. If Twitter tried to crack down or ban the practice, it would face an internal leftist revolt and an external assault from the media that would cost those responsible for doing the right thing their jobs.

If not their lives and careers.

It took off. Weinberg didn’t know what “doxing” meant, but it was happening to him: Someone posted his address. Detective Lopez didn’t answer his call, but soon someone with the police department contacted Weinberg to let him know that officers would be patrolling the area around his home because he might be in danger.

Strictly against Twitter rules, yet Olivia Nuzzi keeps the woman’s name who did it anonymous. That’s a privilege her victim didn’t receive. Doxing is only meant to work one way. You do to the center and the right, never to the left.
