What is the user data policy in regards to AI here?

Are posts and comments being used to train AI either at digg or externally?

The closest thing I can find is in the privacy policy: "For research and development. We may use your personal information for research and development purposes where it is in our legitimate interests to develop, analyze and improve the Services. As part of these activities, we may create aggregated, de-identified, or other anonymous data from personal information we collect. We may use this data and disclose it to third parties for our lawful business purposes, including to analyze and improve our services and promote our business."
