 Project Chanology began its campaign by organizing and delivering a series of denial @-@ of @-@ service attacks against Scientology websites and flooding Scientology centers with prank calls and black <unk> . The group was successful in taking down local and global Scientology websites intermittently from January 18 , 2008 until at least January 25 , 2008 . Anonymous had early success rendering major Scientology websites inaccessible and leaking documents allegedly stolen from Scientology computers . This resulted in a large amount of coverage on social <unk> websites .
