I know this is an old threat but just adding in that I, too, rely on TA while also trying to review hotels and restaurants as I travel. After more than 100 hotel reviews, I would think that my reviews no longer require close scrutiny. Most of my reviews go through and are posted within a day.
But I submitted a review 6 days ago that is still pending review. I can only guess that it's because I highlight a regulatory problem by the hotel, which would be hard to substantiate independently (I wish I took a photo of it). I can't tell if TA is worried about libel from posting ... or if TA is in the hotel's pocket. Either way, disappointing.
