The site has been linked to Internet subcultures and activism groups, most notably Anonymous, the alt-right and Project Chanology. 4chan users have been responsible for the formation or popularization of Internet memes such as lolcats, Rickrolling, "Chocolate Rain", Pedobear, and many others. The site's "Random" board, also known as "/b/", was the first board to be created, and is the one that receives the most traffic. The Random board has minimal rules on posted content. The site's anonymous community and culture have often provoked media attention.
