On March 28, 2008, "Wired News" reported that "Internet griefers"—a slang term for people whose only interests are in harassing others—assaulted an epilepsy support forum run by the Epilepsy Foundation of America. JavaScript code and flashing computer animations were posted to trigger migraine headaches and seizures in people with photosensitive or pattern-sensitive epilepsy. According to "Wired News", circumstantial evidence suggested that the attack was perpetrated by Anonymous users, with the initial attack posts on the epilepsy forum blaming eBaum's World. Members of the epilepsy forum claimed they had found a thread in which the attack was being planned at 7chan.org, an imageboard that has been described as a stronghold for Anonymous. The thread, like all old threads eventually do on these types of imageboards, has since cycled to deletion.
