So because your review doesn't get posted, there must be a conspiracy ?
I suppose its possible but other more likely reasons include;
- You haven't waited long enough - when did you send it?
- The email TA sends you (that you have to reply to) after you send in a review got caught by your spam rules and is currently residing in your spam/junk mail folder
- You did see the email but forgot to click on the link
- You posted something outside the review rules.
To ease your conspiracy-theory fears, there are plenty of hotels with very poor reviews, if you want to check that just pick a place and look at the lowest rated hotels there.
Here's one at random for example tripadvisor.com/Hotel_Review-g60763-d290982-…
"I'd rather take a nap at the Macy's bathroom than this place" ... etc
