Ms. Firdaus - Thanks for the reply.
However, there are other rules under the Information Technology (Intermediaries guidelines) Rules, 2011. An article (link here) is written where the Supreme court declined a petition by Mouthshut.com regarding such reviews. Can you elaborate more on this if you have more knowledge about these rules?
Also, mouthshut.com uses search engine optimization to display their reviews on top of google when anyone is searching for any brand. A simple search for "airtel digital tv review" or any other brand name will lead to their website.
These content is not approved or even verified. Most such reviews are just opinion and can be work of competitors. Can we send a legal notice to them on any strong ground to remove such content or threaten them with legal action?
