The Borg and/or Scavengers have all three scanning exotics on and their
entire fleet on long range scanners.
The Privateers and Lizards seem to have at most the first scanning
exotic on. Or perhaps their closer ships to you are on passive scanners
since they have cloakers and semi-cloakers.

I believe that is a long standing bug that no one has yet found.
But it does not appear in every game.
It only appears under a specific set of conditions.
I believe the sharing of contact info triggers this bug somehow.
