No. It won't show up on your wall or anyone's Newsfeed. Your friends will not know unless you tell them. Where did you get those ridiculous ideas?

If you report someone on Facebook, it will remain private and between you and Facebook developer/workers. No one else will know unless you tell them, so.

Hope I helped! If you any other questions, add Additional Details and I'll try to help you out.

Good luck and best of wishes.
