A publisher can get disfellowshipped for gossiping about a pedophile. A pedophile molested his own child but showed the elders that he was repentant and still lived with his family. This child had told your child about her dad molesting her. Your child told you. You notice that a sister was letting her daughter spend the night with the pedophile's daughter. If you warn this sister in order to keep her daughter out of harms way you can be publicly reproved or even disfellowshipped for 'gossiping about the pedophile"
It does not matter that you are trying to protect a child!
