I've written alot of trip adviser reviews and never had a problem having them post. I also rely on reviews when I travel. It's pretty easy to weed out the people who slam a place because of a one-off bad experience which wasn't the hotel's fault (I also weed out the reviews from shiny-happy people who love everything...the truth is always somewhere in between). If you see a suspect review, report it. I did this once when people gave a great local restaurant 1 star because they went on Monday (the one day each week when it isn't open) without checking the hours first. They didn't even eat there, so how could they write a bad review? The review was promptly removed.
