"Given the enormous amount of speech uploaded every day to Facebook’s platform, attempting to filter out “bad” speech is a nearly impossible task. The use of algorithms and other artificial intelligence to try to deal with the volume is only likely to exacerbate the problem."

"If Facebook gives itself broader censorship powers, it will inevitably take down important speech and silence already marginalized voices. We’ve seen this before. Last year, when activists of color and white people posted the exact same content, Facebook moderators censored only the activists of color. When Black women posted screenshots and descriptions of racist abuse, Facebook moderators suspended their accounts or deleted their posts. And when people used Facebook as a tool to document their experiences of police violence, Facebook chose to shut down their livestreams. The ACLU’s own Facebook post about censorship of a public statue was also inappropriately censored by Facebook."
