In fact, the more you find out about this sub-reddit the more it sounds like Wired is making an erroneous link between the actual problem of vigilante-ism on reddit and some harmless Lost & Found style sub-reddit. If you actually want to follow the thread of reddit's amateur sleuths it doesn't go via /r/RDI it goes via /r/conspiracy. Having spent the entirity of 2016 claiming that Hilary Clinton was party to a secret pedofile ring in a pizza restaurant culminating in a vigilante shooting up the restaurant, they've now moved on. Joe Biden is pedofile this time! They've got video of him making physical contact with children in public spaces in front of cameras to prove it and they're going to run with this one till they've got their man!
I just feel this story is a little ridiculous.
