GoKawiilWhatsApp removes hidden AI instructions telling chatbot not to mention regulators or law
Researchers found that WhatsApp's help-center pages contained text invisible to users but readable by AI systems, instructing an AI not to recommend a data protection regulator or cite relevant privacy law once a user mentioned a lawyer. The hidden notes appeared across 102 blocks on 80 of the 545 help pages, and were removed by WhatsApp between October 15 and October 18, 2026, with Internet Archive snapshots confirming the before-and-after state. WhatsApp told WIRED the text was meant for its support chatbot and appeared due to a bug that has since been fixed.
GoKawiil's interpretation of the reporting above, not reported fact.
The discovery raises questions about whether automated support tools could be steered to withhold information users are legally entitled to, such as their right to complain to regulators under European data protection law. WhatsApp's explanation frames this as an unintentional bug rather than a deliberate attempt to limit user rights, but the episode suggests scrutiny may be needed for how companies embed machine-readable instructions in public-facing pages. The incident could prompt broader examination of hidden AI directives on other corporate help sites.
