420chan
Anonymous forums where users can discuss drugs and alcohol
420chan was an anonymous imageboard founded on 20 April 2005[3][4][note 1] by hacker[5] and freelance web developer[6] Aubrey Cottle.[1] According to its founder, its name was a portmanteau of 420, a slang word originating in cannabis culture but now applicable to drug culture more generally, and 4chan, another imageboard website.[7] Discussion on the site was primarily focused around recreational drug use and wrestling, with other boards related to topics including humor and academia.[8]
While in its early history it was primarily known for hosting a board known as /i/,[note 2][note 3][2] then used by the hacker collective Anonymous[8][9] to stage "invasions" against individuals and web platforms such as Habbo Hotel,[10] and Hal Turner.[8]
The modern incarnation of the website was primarily known for hosting discussions about psychoactive drugs legal and illegal.[11] The site was also known for its LGBT discussion boards, /cd/[note 4] and /sd/.[12][note 5]
