I can confirm. I was on 4chan a lot as a teenager (some ten years ago, now), and the Nazism was generally more a joke about how nasty and intolerant the board was. There were even 'raids' (essentially cyber-bullying) on racists. I can only guess that things must have gone downhill when the site was taken over by Hiroyuki Nishimura, who has some pretty right-wing political views. That said, there's also a kind of natural affinity in the humiliated-outsider-mentality that 4chan had that fits with Nazism in a way that I feel has become more and more clear in recent years.
