how about, "hrm... here are two almost equivalent candidates, oh wait that one sued his last company and ruined their rep"<p>or... what if the HR department of some big company doesn't hire people who have sued their employers?<p>I'm just making things up but I have a feeling there is some potential situation where it would cost me.<p>Also what do I gain from it?  Vengeance is one, not really a good reason.  Helping out the probably not so huge number of other people who might get conned by them in the future is the other.<p>That reason is pretty decent, but weighed against the personal cost to me, not so much.  Also you need to factor in if these future employees would even find my warning.  I did a little SEO testing with this already and it wouldn't be that easy to create something easily discoverable.
