A group with name "Anonymous" successfully carried out a Google Bomb targeted at "Church of Scientology" getting top Google search result for term "dangerous cult", it also seems the group somehow also managed to get "Scientology is a terrorist cult" into Wikipedia entry on Google search result for term "Scientology", the word "terrorist cult" is nowhere to be seen on the current Wikipedia entry and the Google cached page.

Almost a year ago, Google announced to take measures to stop this practice after a Google bomb appeared for term "miserable failure" which bought George W. Bush website as the top result.
