I don't think there is anything wrong if cameras follow a contestant from stage to backstage. As long as contestants and their relatives are eager to air their views, channel will take advantage of such situations. No one forces anyone to say things they don't like.
Maya take the above case. The contestant wanted to keep that part away from public glare but channel house sent the reports to media with the Ph Nos. of the PR of these contestants. So that quotes from Poonam can be taken. The girl was livid when called by media. How fair is that on the part of Channel house then? Did they really do it just keeping the Poonam help factor in mind or was TRP/Money also a part of the thought process for such an act.
