Even worse. I went to a horrible, horrible hotel in Prague (which at the time was the #1 result, don't know if still is). My (obviously) bad review, while polite and with pictures attached, was ignored after 3 weeks in limbo. Not explicitly refused, no explanation. Just poof, never happened. And support is also ignoring my questions. All that being a "Genius" user. Unfortunately I don't have Twitter so no public-shaming-user-support.

Be careful with reviews. They might not be fake but certainly arbitrarily filtered.

I usually check reviews on Google maps and tripadvisor before making a decision on a multi-night stay, but for the 1 nights I can usually get by well enough with photos and the sites own reviews. Though for what it's worth, the hotels that offer the 10% discount for genius members on booking are usually real discounts, but it's about the only "real" thing I look at on booking.

Concur. I always cross-check on TripAdvisor. It sometimes feels obsessive, but on an expensive trip, a bad night can mess up several subsequent days. Hotels/Booking.com are selling, and many of the customers are not frequent travelers -- turkeys ripe for the plucking.

Put the same review on TripAdvisor. In my experience, they are not afraid to host bad reviews and I've always found the reviews there to be informative and indicative of quality.
