So. Here's the plan....
We all know this lunatic has just been released from the nuthouse but clearly as he's larping on 13yo's & asking anyone that communicates with him on discord to cut themselves that he's clearly far from safe to be released back into the public.
So all we need to do it identify which mental house he was admitted to and hope he was using their internal wifi. Pretty sure the guy posted several pics from inside his mental house and was posting actively on this discord whilst being in the loony house, identify which hospital it was.
TLDR: if someone can identify which mental house he was admitted to I'll draft a letter of concern to said mental house. I'll ask them to check their routers and servers history searching for any device that ever visited
4chan.org/bant (almost certainly just this one guy) then once the device has been identified they can check the history of that 1 device, linking him to said discord servers.
There are plenty of screengrabs that have been posted here proving he insists on people cutting & harming themselves, I think a cleverly worded letter would get this guy locked up for years!
