It was revealed during the season that around 100 phone-phreak hackers with power-dialing hardware and software were able to place as many as 10,000 votes a night from a single phone line with the touch of a button. However, FremantleMedia, which produces the show, contended that the hackers have had 'statistically insignificant' effect on the vote. Simon Cowell also insisted that Tamyra Gray's unexpected ouster from the show only strengthened the producers' contention that the voting was fair. Nevertheless, concerns were raised about possible unfairness in the situation of a tight vote. Ken Warwick later said in Season 5 that equipment was put in place afterwards to address this issue but it allegedly has never detected such a problem since.
