This document discusses using veiled viral marketing via social media to disseminate information about stigmatized illnesses. It describes how anonymity allows people to share information about sensitive topics more freely but can also enable unwanted behavior. The study presented tested sending veiled versus unveiled invitations on social media to inform people about HPV and found a relatively high acceptance rate, even for veiled invitations sent via email. However, veiled marketing also presents potential problems like spam and stress that require solutions to implement it responsibly. Further research is needed to understand why veiled invitations are accepted and test this approach with other health topics.
