Facebook – How internal teams respond to reported incidents

QUOTE:  Facebook Safety has posted a note and an infographic that details the internal teams, guidelines and workflows that are involved in the Facebook reporting process. (the image is rather large, so you might have to download it and view it in an editor to view it properly). Facebook has hundreds of moderators based in four centers that evaluate content based on established community standards. The following four distinct teams act and respond accordingly:

1. Safety Team – Violence and Harmful Behavior
2. Hate and Harassment Team – Hate Speech
3. Abusive Content Team – Scams, Spam and Explicit Content
4. Access Team – Hacked and Imposter Accounts

The Safety Team will contact law enforcement authorities when credible threats of violence are present.
