"Tonight concludes Yom Kippur, the holiest day of the year," wrote Facebook founder Mark Zuckerburg in a post during the night. He writes that it is a time "for Jews when we reflect on the past year and ask forgiveness for our mistakes. For those I hurt this year, I ask forgiveness and I will try to be better. For the ways my work was used to divide people rather than bring us together, I ask forgiveness and I will work to do better. May we all be better in the year ahead, and may you all be inscribed in the book of life."

While not elaborating further, Zuckerberg may have been referring to issues involving less than adequate content monitoring on his networks, that include WhatsApp, Messenger, and Instagram, and have become the main and almost exclusive tool by which many communicate and express themselves.

Legitimate content is widely reported to being deleted from the network, with users blocked or receiving warnings that they will be blocked without explanation, including journalists and bloggers who criticize it. On the other hand, Facebook is unable or unwilling to control the voluminous calls for violence commonly found on the networks.
