In the night between 17 and 18 December the housemate Matteo Casnici, during a conversation with Davide Baronicini and Francesca Giaccari, accidentally uttered a blasphemous expression: the incident was the subject of much controversy, especially by Catholic viewers, who following the program.
The Catholic daily Avvenire also lashed out against the broadcast by publishing an article in which the reality show was accused of making a spectacle of the offense against God and the good education that unites believers and non-believers.
Subsequently, on January 8, 2011, due to a deplorable episode that occurred inside the house, the authors unexpectedly canceled the weekly televoting between the three housemates at risk of elimination, namely Giuliano Cimetti, Olivia Lechner and Pietro Titone.
Following this event, there were further controversies and the issue of blasphemies on TV has aroused strong negative reactions from many Italian religious associations; for this reason and for the low level reached by the housemates of this edition, Mediaset, publisher of the reality show, in the episode of January 10, 2011 considered it appropriate to intervene with an official statement in which it ejected all the housemates guilty of having uttered a curse inside of the house, namely Matteo Casnici, Pietro Titone and Massimo Scattarella (who pronounced a blasphemy during Grande Fratello 10).
For some months, in fact (precisely from 3 September to 15 December 2010), the public was asked to vote by sending a text message, a presentation video uploaded by the aspiring competitors on the official website of the broadcast.
For this reason, the antitrust has also been interested in opening an investigation into the televoting system, which will examine the positions of RTI, Telecom Italia and TXT Polymedia for the next few months in order to establish whether or not there have been violations to the detriment of viewers.
