Disparate individuals working under the banner of "Anonymous" initially congregated on the online collaborative community 4chan (a description of the group, its motives, and its goals can now be found here). Their efforts to draw attention to the Church's "campaigns of misinformation" and tendency to suppress dissent have generally been successful: The first coordinated raid against the COS, a denial of service attack, crashed the Church's website. Anonymous members subsequently bombarded the Church with calls in order to tie up phone lines, sent "black faxes" to waste ink, and also "Google bombed" the Church by tying the word "Scientology" to such nefarious terms as "dangerous" and "cult" in order to skewer search results. A complete rundown of the attack, dubbed "Project Chanology," can be found here. On the site, February 10 is cited as the day of reckoning for Scientologists.
According to our source, the Church is arguing that such attacks on their physical plant and website constitute "illegal interference with business." The CoS is also said to be playing up its nominal role as a religious organization in order to claim that efforts to disrupt its operations are a violation of the Church's First Amendment rights, and thus technically constitute hate crimes.
Initial attempts by authorities in Los Angeles to track the IP addresses used by some of the pranksters have allegedly been successful. Calls to the U.S. Attorney General's office in L.A., the LAPD, and the FBI, however, have not yet been returned.
