IMO Trip Advisor is a dreadful site. My business and those of very competent hoteliers here were much maligned by deliberate spiteful posts that were evidently just that, yet Trip Advisor refused to do anything about removing or even flagging these posts. They're still there. I have often implied that I regard AC.com as too heavily and partially moderated, but I infinitely prefer that to the way that Trip Advisor is totally unmoderated.
