Anonymous decided that the Church of Tom Cruise was a cult and was causing harm to those who follow it. They launched an online offensive against the church, including phone, fax and e-mail spamming, and DDoS attacks meant to crash the site. The hackers also employed "Google bombing" which caused the search engines to pull up the official website as the top result for searches like "evil cult." The hacking was more annoying than debilitating, but Anonymous caused enough of a stank to have the global community pay attention.
