WhatsApp help pages leaked Meta chatbot's hidden instructions

About 80 WhatsApp help and FAQ pages exposed hidden instructions written for Meta's own large language model in the web page code. After WIRED contacted it, Meta removed the relevant text from all pages and said this was a fixed bug. The privacy company Redact found about 100 passages of hidden text in these pages, in a code block titled HelpContentGalaxyLLMInclude, which included a section named "WHAT NOT TO SAY" and explicitly required that legal advice not be provided to users. Some instructions required the bot, when a user mentions litigation, a lawyer or a court, not to cite or explain the WhatsApp Terms of Service or Privacy Policy, not to mention privacy regulations such as GDPR, LGPD and CCPA, and not to suggest that users contact data protection authorities or regulators.
