I just browsed through all the reviews of policybazaar here on mouthshut and it appears all the reviews giving a higher rating are given by fake profiles. Logic behind this:
None of them has a photo
All have given only 1 review till date
As a matter of fact the whole concept of mouthshut is not very robust, For most of the services which are reviewed here on mouthshut one will only find only negative reviews as people who find the service good wont write a review at all. Mouthshut should try to bring a representative sample data to review here for every service.
