Last December, authorities arrested Edgar Welch, a 28-year old man from Salisbury, North Carolina, who had entered Comet Ping Pong, a Washington, D.C. pizza parlor, armed with a shot gun. Mr. Welch reportedly came to Comet Ping Pong on a self-described mission to free child sex slaves that he believed might be imprisoned there at the bidding of Hillary Clinton and her campaign Chief of Staff, John Podesta. After Welch shot his gun into the ceiling, terrified employees fled the building. Then, after encountering swarms of local police, and having found no evidence of the vast conspiracy he had been led by social media to believe existed, he gave himself up peacefully to authorities.

As outlandish as the story may seem, Mr. Welch was not the only one duped by the story. For weeks, dozens of anonymous posters had fanned the flames and pursued the imaginary conspiracy theory on Reddit.com, a hugely popular social news aggregation site.

This fake conspiracy was likely fueled in part by armies of “bots,” which are fake social media accounts often purchased and organized centrally, and mobilized to push a particular opinion or agenda and sway public opinion. It is surprisingly easily to purchase bots online. For example, Russian websites, such as BuyAces, sell empty social media accounts to anyone willing to pay with digital currency. Once purchased, programmers can enable these accounts to disseminate information or respond to news stories en masse. It is widely reported that Special Prosecutor, Robert Mueller, is investigating whether the Russian government used such tactics to influence the last election.

What does this have to do with advertising, you might ask? Everything.
