I posted a review for a restaurant last month, then I visited that same facility this month, within 30 days, and TripAdvisor will not allow me to write a review within 30 days, why?

The reviews are the basis for the various rating systems in place. If you could place reviews any time you wanted to, you would have undue influence over the ratings. As is works, older reviews count less than the newer reviews. So the wait time helps keep it fair.
Allowing one review per 30 days is extremely reasonable. There has to be some kind of limit. Otherwise, some people would post new reviews of the same business on a weekly, daily, or even hourly basis.
Especially if they received some form of compensation for reviews.

Can any of you knowledgeable people tell me the reasoning behind why you have to wait 30 day before re-reviewing a restaurant but 3 months for a bar.
Probably overlooked when they grouped bars in with attractions.

In my destination, there are no bars that aren't also restaurants, so it couldn't happen to begin with.
Edited: 2:44 pm, February 12, 2013Yep, bars are attractions. Go figure, but that's the way it is ;-)

Fred D, if TA did not have a restriction on how frequently a member could submit a review, then some members could submit reviews on a daily basis for the same restaurant, over and over. It would not take long before the rankings would go completely crazy!
It used to be we could submit *only one* review, ever, for any place we visited.
Only TA Staff know why a resto cannot be reviewed before 30 days go by. For the guidelines that TA have established about writing reviews, have a look here ... especially the link in the section that says "unique and independent."
