I came across a recent post that went viral @ facebook (16800+ shares and thousands of comments) with regards to car service provided by Hyundai Australia. This is becoming a very common "trial by social media" nowadays. Hyundai Australia is able and capable to deal with the negative post professionally and has not threatened Facebook to take down the post immediately in any means. I applaud the Ozbargain decision not to take down the recent post (http://www.ozbargain.com.au/node/98410) despite potential legal treat(s).
I'm assuming the post could still be removed if certain developments were to continue to pan out. But yes, for now, good on OzBargain for leaving the post published. Similar occurrences have happened in the past eg. McDonald's not allowing posts because of trademark infridgements. Running a website such as Ozbargain must mean Scotty has his lawyer on speed dial. :-)
Regarding Facebook and Hyundai, well there's just no match. Facebook has a huge army of lawyers and have covered themselves thoroughly in their policy design.
BTW, do you know personally that Hyundai have not been in contact with Facebook regarding the particular post in question? Hyundai may have no choice at this stage other than to put on a professional face.
