Ehh, I saw plenty of it on the pretty big sites I trawled. Whether that was moderators failing or just allowing people to talk, I can't say, but it was hardly contained to one weird corner of the internet. There were also super widespread rings like HentaiFREE proudly proclaiming that the site displaying their button was morally pure and above all those anime boobs (and simultaneously condemning every site that had even "artistic nudity" - there was a kerfuffle over whether or not showing the original senshi transformations with the lines would make a site "hentai".) Different self-righteousness? Sure. But it was absolutely there.
