In the country of the Holocaust, the commitment against hate speech is as fierce as the commitment to free speech. Hitler’s “Mein Kampf” is only available in an annotated version. Swastikas are illegal. Inciting hatred is punishable by up to five years in jail.

But banned posts, pictures and videos have routinely lingered on Facebook and other social media platforms. Now companies that systematically fail to remove “obviously illegal” content within 24 hours face fines of up to 50 million euros.

The deletion center predates the legislation, but its efforts have taken on new urgency. Every day content moderators in Berlin, hired by a third-party firm and working exclusively on Facebook, pore over thousands of posts flagged by users as upsetting or potentially illegal and make a judgment: Ignore, delete or, in particularly tricky cases, “escalate” to a global team of Facebook lawyers with expertise in German regulation.
