I don't see how a warning in this instance is helpful. Knowing that the data was likely scraped somehow from Facebook, what is the rational and data-driven approach to take? Unless there is a specific set of actions known to mitigate the risk of additional information leakage, saying "be careful with Facebook" sounds nice but doesn't help anyone. So why not let Facebook's security team do their due diligence first and then fully disclose the information later?
