I was looking for reviews on dentists. I thought I would try insiderpages.com. I found a dentist close to me that seemed too good to be true, the office had twenty reviews all of five stars. Not a single one was four stars, or three, etc. So that stuck out as odd, but not impossible. But then I did some digging, reading the reviews they all seemed too perfect. Not only was the dentist awesome, but also the front desk guy Ben. Also the writing style of the reviews seems suspicious, no misspellings, no grammar errors, and similar styles. And to top it off, 100% of the reviews were rated as 100% helpful by any where from a few people to twenty people. 100% of the reviews were helpful, that also seems very odd.
So more digging and I find that out of the twenty reviewers, not one, not a single person had posted a review for anything else. That is very odd for a social site.
So next I did a test, I rated reviews as not helpful to me, as they truly weren't. It showed that some reviews were not 100% helpful any more, good sign. I checked later and it still showed that some weren't helpful. But the next day all the reviews were back to 100% helpful again. So they censored my reviews of the reviews.
I also posted a review that was not positive, and it showed fine for one day, but by the next day it was gone.
So good reviews stay, but negative ones don't. What a scam. You have been warned, (assuming that this site doesn't' also remove this negative review.)
