I’m not under the impression that all loliposters are by definition pedophiles, but the ones who jerk off to that trash absolutely are. An example of non-pedo loliposters would probably be DRC users, who bombarded me with them a while ago to get a rise out of me. Believe it or not, I do get the psychology of sending people this sort of thing just to get a rise out of them.
But I also think sexually explicit lolicon and gore are two cases where people are right to be disturbed by the content they’re seeing and want their sysadmins / instance admins / etc to be proactive about suppressing it. Sending me raped lolis isn’t really “content,” it’s just trollan trying to trigger lames.
