I flagged most of them. Hopefully that will reduce the number of dupes
Not sure what flagging will do other than add to the mods workload; the point was if any of these submitters just upvoted the existing posts instead of submitting a new source this story would probably have been on front page a week ago. ¯\_(ツ)_/¯
On the contrary. I emailed the mods and dang said "flag the post, it'll get marked as a [dupe]."
