What happens when you report something on Facebook? It can be from anything from racist, sexist and offensive content or comments. Facebook Security posted an explanation of what happens.
The guide above isn't all that straightforward. While the company breaks down the process, explaining it in four teams (Safety, Hate and Harassment, Access and Abusive Content), it's made up of hundreds of employees that are monitoring complaints 24/7. From Facebook:
If one of these teams determines that a reported piece of content violates our policies or our statement of rights and responsibilities, we will remove it and warn the person who posted it. In addition, we may also revoke a user's ability to share particular types of content or use certain features, disable a user's account, or if need be, refer issues to law enforcement. We also have special teams just to handle user appeals for the instances when we may might have made a mistake.
