Hugh Pickens DOT Com writes "Reddit became a gathering place for amateur sleuthing in the aftermath of the Boston Marathon bombing earlier this year, fueling what some reports called 'online witch hunts' that resulted in some people being falsely identified as the bomber. Now Andrea Peterson reports at the Washington Post that a section on the popular online community for finding the Navy Yard shooters has been banned. 'We banned it because it violated site rules by encouraging the posting of personal information,' says Erik Martin from reddit. The shooting at the Washington Navy Yard on Monday morning left at least 12, including a gunman dead. But police say there may be another suspect at large, and they 'have reason to believe' this individual was involved in shootings."
