According to the current law, the public release of private photos of others is an invasion of privacy and involves the protection of personal privacy. It is usually considered illegal for an original artist to publish a photo of Xiao San on social media platforms such as Tik Tok without the photographer's consent, which will infringe on his reputation and privacy. In many countries and regions, including China, infringement of others' privacy will be punished by law. The original distribution of San Xiao's photos will face legal responsibilities, including civil compensation and criminal punishment. If you encounter similar situations, it is recommended to consult a professional lawyer and seek specific legal advice and help.
