We recently spent over 30 days in Cambodia & Vietnam and I submitted quite a few reviews, one was removed by trip advisor with an email to myself saying the review wasn't mine. We decided to email trip advisor all the emails we received from the hotel trying to bribe us with offers of free accomadation when we return or even paying for our lodgings in HoiAn. That was over a month ago and we still have heard nothing from TA, I am starting to wonder whether it is worth doing reviews etc. TA in there original email accused me & my family of fraud which is why we sent them our correspondence from the hotel. By the way the hotel is ranked No 1 in Hue, perhaps because they bribe reviewers.
