I know for an absolute fact that many of the rave reviews for dive companies on Trip Advisor and Scuba Board, plus a lot of others, are written by the same people that own the companies, their friends, family, all that, like that JJ Diver guy that got busted here. Scuba Board edits ALL of their posts because they are being sued for millions of dollars, for running a moderated board. I think that's the big difference here. The board is not moderated to they don't have the liability issues, and apparently no financial incentive to skew the reviews or ratings.
