Facebook bans Robinhood Stock Traders group: Amid a Wall Street market battle that primarily used the stock trading app Robinhood, Facebook cracked down on a related group. A group called "Robinhood Stock Traders," with 157,000 members, was shut down by Facebook. The shutdown notice claimed that it was for a violation of standards against "adult sexual exploitation," but it is unclear what this might be referring to. The group's founder believes that the real reason was because of the controversy surrounding the market battle. According to The Guardian, "Facebook spokeswoman Kristen Morea said, 'This group was removed for violating our Community Standards, unrelated to the ongoing stock frenzy.' She did not respond to requests to elaborate." 

***UPDATE: Days later Facebook restored the Robinhood Stock Traders group without any explanation for the reversal. Read more about this story on Newsbusters.
