The race to prevent ‘the worst case scenario for machine learning’

Dave Willner has had a front-row seat to the evolution of the worst things on the internet.

He started working at Facebook in 2008, back when social media companies were making up their rules as they went along. As the company’s head of content policy, it was Willner who wrote Facebook’s first official community standards more than a decade ago, turning what he has said was an informal one-page list that mostly boiled down to a ban on “Hitler and naked people” into what is now a voluminous catalog of slurs, crimes and other grotesqueries that are banned across all of Meta’s platforms.
