Chat records published by Tik Tok, if involving private content that can expose the identity information of the other party, will constitute a violation of privacy and reputation, and the other party can sue you and demand compensation according to law.
Chat record is a kind of privacy between people. Even if you really want to make it public, you should get the consent of the other party in advance, or hide the avatar and name of the other party to prevent others from identifying the identity of the other party from the chat records.
