“Russia has banned social news site Reddit for ‘promoting’ use of illegal substances. The site is believed to have been banned over a discussion about how to cultivate hallucinogenic mushrooms on one of its 9,000 active forums. The Russian media watchdog said it had tried to contact Reddit about the chat thread but had got no response. Earlier in the week the same agency threatened to ban Reddit for discussions about growing marijuana.”
