I am NOT an attorney..but I do have a professional experience in these issues.
The most negative and potentially libelous posts are those by Streetbeast (self admitted or discovered )personnel (or "ex-employee
The characterization of sales practices, shoddy workmanship, the interference with competitors sales, are all actionable, and admitted to in these posts.
In the course of the "research" I think the tort damage is actually of these posters. The comments made after the inciting comments are in response to statements..response to fictitious posters with known IPs.
Further, my understanding is, you commit slander or libel, with FALSE statements. It is not libel to post a court document, a adjudicated settlement, or factual incident.
A company or person that posts libelous statements about ITSELF and attempts to claim to be harmed would be very..very foolish.
It will be interesting to see if this is just blowhard BS..or true stupidity..
