The latest story out of the hothouse of stupidity that is 4chan/8chan is that they’re targeting tumblr users for harassment — with the specific intent of identifying troubled young people who have admitted to self-harm, and then goading them to commit suicide.
The trolls also wrote that they plan to post gore and self-harm photos in popular social justice and fandom Tumblr tags, as well as target individual users with anonymous messages, in an effort to pressure them into committing suicide.
One of their targets is any fan of some show called Supernatural, which I have not seen (although now I’m putting it on my list of shows to check out). There may be a hint of pathological skepticism here — people who like shows about supernatural phenomena must be subhuman, and therefore are acceptable victims.
