Hollywood Reporter: Milo Yiannopoulos, an alt-right hero known for his banishment from Twitter, is preparing a bid to acquire his own social media firm: 4chan. Launched in 2003, 4chan is an imageboard internet site that allows users to post anonymously. Its roots were in anime and manga, though it has evolved into much more and has facilitated some controversy, including allegations that it allows for cyberbullying.
