I agree. Over the past 4 years my business has had 16 five star reviews, and never anything less than a five star review.
Suddenly, there are a bunch of poor ratings on my business's page, mostly from anonymous "A TripAdvisor Member", and all occurring within the last few weeks, many of them on a single day.
There is no way that these are legitimate ratings from someone who attended our event. Either my competition is sabotaging my business, or there's a glitch in the system.
Where is the accountability for these ratings?
I think most business owners are generally friendly towards TripAdvisor, and many of us promote it on our websites because it has always been fair to the business owner AND the traveler (unlike Yelp which filters most of our legitimate reviews).
I've always promoted TripAdvisor on all of my marketing and promo materials, website, and social media. This ratings thing is a bad move. I'm taking their badge off my site until they get this right.
