On April 15, 2013. Public Citizen reported on a lawsuit against a South Carolina person by an Ohio company, Med Express, when she refuse to remove a negative review from EBay after a snafu over a customer service issue (a postage due amount). The company wanted to keep a perfect “reputation”. Paul Alan Levy has he story here. If Ohio had an effective SLAPP law, of there was effective federal law, this wouldn’t happen. EFF followed with an article April 25 by Adi Kamdar here.
Public Citizen has a link on the case here,(note the mention of a Texas anti-SLAPP law on the "motion to dismiss" comment), and Bloomberg has a brief description inside this long article about many i.p. cases, here.. There is a link on Facebook to a report that apparently gives the plaintiff's side of the story, here.
