There has been many crimes linked to 4chan, one man even killed his gf and posted the pics there. Someone reposted the naked, lifeless pics of her on there, where he talked about her son would be home to find her murdered soon. It's a sick subculture and can only breed bad things. And almost all these people have a web presence.
ETA: the pics above were posted today, in the thread about these shootings.
ETA 2: how many of these people do we find have extremely disturbing stuff online?
there is no proof as of now that this incident has any connection to 4chan, there is some speculation.
before calling for action to be taken i think we should wait for proof.
im not talking about any other case, im talking about this one.
