I think 4chan and its descendants (which include[s|d] SCP) may be the exceptions that prove the rule, as they bought in to the "be slightly evil" advice pretty hard.
I think history will prove it was not in the real scheme of things.
However it is still full of sociopaths working on their own nefarious deeds!
Additionally: 4chan isn't a subculture, it is/was a subculture incubator.
