Race recognition from social media? Definitely possible. But linking that to a mobile number is the interesting part.

People have bad cyber hygiene in general but most people know not to post their mobile on their social media publicly.

The question that comes to mind is what percentage of black Facebook users have their phone number on their profile (only visible to their friends) and have also friended a bot? (or joined a group that compromises their security?) A fraction of a percent is still enough to do some harm.

All you'd need to do is join dark web data to social network data. Phone numbers are common parts of those data sets.
