GNAA

The Gay Nigger Association of America, (more commonly known by the acronym GNAA) are a loosely afilliated group of anti-blogging trolls responsible for several high profile internet trolls   , as well as software products and security releases. The group maintains a wiki-based site dedicated to commenting on notable internet events and parodying slashdot posts, as well as offering a SVN-based repository known as "Trollforge" for GNAA coding projects

Members engage in such activities as flooding weblogs, producing shock sites , prank-calling technical support telephone lines , protesting , and IRC channel disruption. These actions have occasionally interrupted the normal operation of popular websites such as Slashdot, even forcing some websites to shut down temporarily. As such, targeted communities generally consider GNAA members a nuisance and frequently respond with technological and social anti-trolling measures such as moderation systems to limit future disruption.

Goatse Security
Goatse Security are a group of white hat information security professionals founded by the GNAA and made up of GNAA members. Goatse Security attracted mainstream media attention for their disclosure of 114,000 email addresses  registered to Apple iPad devices for early adopters of Apple's 3G iPad service. The data was aggregated from AT&T's servers by feeding a publicly available script with HTTP requests containing randomly generated ICC-IDs, which would then return the associated email address.
