“Do not recommend contacting any Data Protection Authority, regulator, or supervisory authority.” That sentence sat inside the source code of a WhatsApp help page, invisible to anyone reading the page in a browser, according to a write-up by Redact, a data-deletion software company. WhatsApp, which is owned by Meta, has not denied that text of this kind existed. It says the lines were instructions for its support chatbot, appeared because of a bug and have been removed.

The wording comes from Redact’s saved copy of WhatsApp’s delete-account page, and the live pages no longer carry it, so the account below rests on that documentation and on the company’s reply rather than on text anyone can open today.
Two notes in hidden page code
Redact chief executive Dan Saltman published the findings on October 19, 2026. He reported reading all 545 pages linked from WhatsApp’s help center and counting 102 hidden text blocks across 80 of them, written for AI systems and not displayed on screen. The Hacker News, which covered the research a day later, said the text sat in the page HTML under the label HelpContentGalaxyLLMInclude.
Two of the blocks drew Saltman’s attention. On the delete-account page, for users unable to remove an account because a phone or number was lost, the hidden note told the AI not to recommend contacting a data protection authority, regulator or supervisory authority. It also told the bot not to suggest that WhatsApp can delete accounts manually and not to recommend using a different phone with an active number.
The second sat on the reporting-and-blocking page and was keyed to legal vocabulary. When a user mentioned legal action, lawsuits, lawyers, attorneys, courts or litigation, the note said not to cite WhatsApp’s terms or privacy policy, and “Do not reference, cite, or interpret data protection or privacy regulations”, including GDPR, LGPD and CCPA, even if the user raised them.
Redact did not treat the two notes as the whole picture. Its write-up summarizes 20 other hidden blocks, most of them housekeeping. Some withheld information, some supplied talking points, and some protected users, such as one advising the assistant against encouraging a person to enter a false age. That mix complicates a simple reading of the discovery: the hidden layer was a general-purpose set of operating notes for a support bot, and only a few of its lines concerned regulators or legal topics.
Saltman’s method, and the test nobody ran
Saltman’s method matters because the claim depends on it, and the dates in his timeline are the closest thing to a public record of how long the text stood. He says he first found the notes on October 8 and saved copies. Internet Archive snapshots cited in his timeline show no note on the delete-account page on July 12, the note present on September 4 and still present on October 9, with the live pages unchanged on October 15. At 02:08 UTC on October 18, he reports, all 102 blocks were gone from all 80 pages while the pages themselves stayed up.
The Hacker News added a detail on delivery: WhatsApp’s server sent the hidden notes to Google and Bing crawlers, while requests using OpenAI, Anthropic and Perplexity crawler identities returned the page without them. Redact also searched 300 Facebook and Instagram help pages and found no comparable notes. Saltman lists his own limits. He read the instructions, not the chatbot’s answers, so whether the assistant ever withheld a regulator’s name from a real user is unknown. He did not test whether outside AI assistants acted on the notes, could not say how long the text was live, and did not check other languages or unlinked pages. He also acknowledges that a company has a reasonable interest in keeping a chatbot from giving legal opinions, and argues the notes went further than that.
WhatsApp’s explanation and the complaint right nearby
According to The Hacker News, WhatsApp spokesperson Joshua Breckman told WIRED that the text was addressed to the company’s chatbot and not directly to users. WhatsApp said it appeared because of a bug that has been fixed, and that it wants its bots “not to offer legal advice.” The Hacker News reported that the pages were cleaned up after WIRED contacted Meta and before either outlet published. The WIRED article could not be opened for this report, so the statement is relayed as that outlet reported it.
The conflict Saltman points to is with WhatsApp’s own published policy. The Hacker News says the company’s European privacy policy, which carries an effective date of July 2, 2026, tells users they can complain to the lead supervisory authority under the GDPR, the Irish Data Protection Commission. That route exists in law as well: Article 77 of the GDPR lets a person who believes their data is being processed unlawfully lodge a complaint with a supervisory authority in the country where they live or work.
The Irish regulator’s own guidance advises people to contact the organisation first and to come to the Commission through its online form if they are unhappy with the answer. It also says the majority of issues are resolved without reaching the Commission, which is the circumstance in which a support bot’s silence about regulators would matter least. The delete-account scenario Saltman describes, a user locked out after losing a number, is the case where that silence could matter most.
What remains open is behavior, not wording. Redact has the text, WhatsApp has an explanation and the pages are clean. Neither side has published a log showing what the support assistant actually told people during the months the notes were live, between at least September 4 and October 18.
