I believe that blacklisting is something that happens in cases like this, and I wonder how it gets coordinated. Especially when there's no public record of a court case. Simply that every time her previous employer was called for a reference, they gave her an unflattering one? Or is it more proactive, like some sort of list that's known in the HR world of certain industries?

Employers aren't supposed to call previous employers for references unless you OK it first, and many employers have explicit policies to not give references because of the potential for being sued.

Of course, it does happen, in various ways. The way to find out is to find a sympathetic recruiter (or, a "recruiter" who's really your friend), and have them call for a reference for you. There's good fodder for a lawsuit here.
