When something gets reported to Facebook, we review it and remove anything that goes against the Facebook Community Standards. If you are reporting messages, the reported messages may be used to help us improve our systems for reviewing other reported content that may go against our Community Standards. We don't include any information about the person who filed the report when we reach out to the reported. Please keep in mind that reporting something to Facebook doesn't guarantee that it will be removed.
If you see something you don't like on Facebook but you don't think it goes against the Community Standards, learn what you can do. If something isn't working on Facebook, let us know.
