I’ve also seen the reverse happen recently.

A neighbor listed their house, then watched through their many home cams as people came for viewings.

As they walked through the house she looked them up on social media, made easier having actually seen them to match faces to names.

Then start ranking prospective buyers by their social media profiles, and behavior in her house as they looked around. The cams have mics so she could hear comments too.

Overall was pretty horrific to see how she profiled people.
