What is Section 230?
"Section 230 is a provision of the 1996 Communications Decency Act. A number of tech industry observers say it's the most important law protecting free expression online. The provision essentially protects companies that host user-created content from lawsuits over posts on their services. The law shields not only internet service providers, like AT&T, Comcast and Verizon, but also social media platforms, like Facebook, Twitter and Google." —CNET
