2channel and its successors are more controversial than other social media in Japan; they are extremely popular among Japan's extreme right-wing, known as the "netto-uyoku", who post xenophobic comments, often targeting Koreans. Defamation is of particular concern; by August 2008, Nishimura had received more than one hundred lawsuits for defamatory comments left on the website. Announcements of crimes also have drawn scrutiny towards 2channel and its successors. In 2012, 2channel was accused by the Tokyo Metropolitan Police of allowing its platform to be used by amphetamine dealers, although no charges were filed.
