I think the difference between Kitten and the BB10 lot, as well, is that most of the BB10 house rebelled, whereas it was just Kitten in BB5. While the other housemates found her amusing, when it looked like it was going to impact negatively on them she lost her support. Whereas people moaned about Siavash, but broke the rules in their own ways, and everybody moaned about everything that everybody did in that series so moaning about people breaking the rules was just part of the ordinary background noise.
