I have found many messages here which says "only constructive criticism is allowed". I am not sure what is defined as Constructive criticism. I have found that the fans cannot withstand any type of criticism for their favorite contestant. So I really fear to put any topic which criticises a good contestent, thinking about the reaction of their fan club.
Another thing I have noticed that, any topic which compares between two contestants, is not taken wisely by the fans. Some of the boring comments are like "You cannot compare amongst them because both of them are great". Come on… this is a competition and we have to compare amongst them and analyze who is better on what and where is the scope for improvement. Otherwise this forum will be nothing but an array of fan clubs where any criticism may tagged as "not a constructive criticism" and only goody goody words about their favorite contestants are allowed
