I think a claim of bigotry is stretching it a bit. The comments/jokes were insensitive at the worst, but not more offensive IMHO than portraying yourself as a shopper for a MSC if you do indeed work for said MSC. That is...assuming this MSC is real.
If the company was a fraud, then comparing it to a Nigerian scam would be somewhat more insulting, as I've never seen a Nigerian scam with anywhere near this degree of sophistication.
My guess is that it's real, and that the poster(s) is/are indeed based in India. The names used are are common Indian names, and the fee quoted for the shop was in Rupees. Neha is commonly a female name and Rohit a male name, as I understand it, so perhaps it's possible that it indeed is two people posting from the same IP address.
Rohit was somewhat off-base, however, as 500 Rupees is equal to over $7.50 at the moment. None-the-less, the low fee does add some legitimacy to the claim that they are indeed attempting to operate an actual mystery shopping company. The fabrications and poor design of the website lead me to believe that the company also lacks some of the traditional values we expect from a MSC in the west, and I would be hesitant to do business with them based on that alone.
