Why it matters for readers: It shows that websites can hide content meant only for machines, which can change what AI tells people.

  • Hidden, non-visible text in WhatsApp help pages instructed an AI not to recommend a data protection regulator.1
  • The researchers inspected all 545 pages linked from WhatsApp's help centre and saved copies on October 8, 2026.1
  • They found 102 hidden blocks across 80 pages, most harmless, but two blocks were notable for their directives.1
  • On the account deletion page, visible text said deletion must be done inside the app with the number active and described waiting periods; hidden text repeated those periods and added three orders for the AI.1
