introduction

We live in an era of increasing worry that internet platforms like Facebook or
Twitter, which mediate our online speech, are also fomenting hatred, spreading
misinformation, and distorting political outcomes. The 2016 US presidential
election, in particular, unleashed a torrent of concern about platform-borne
harms. Policymakers around the world have called for laws requiring platforms
to do more to combat illegal and even merely “harmful” content.
