I've looked into those sources as well, and the only source I can find linking him to alleged pedophilia is a chat conversation between him and another member from the Blockland forum mentioned here, posted on that forum by the other member and then reposted a second time later.
The chat, assuming for the sake of argument that it isn't a forgery, when read in its entirety, comes across as poorly judged sarcasm between two acquaintances, an unfortunate combination of shock humor and dry humor that is less clear when written and/or online.
From what I've seen, Moon has never made this argument himself, and is probably wise to have refrained from doing so, since in any case of hearsay like this, not responding is the only way you can really handle it; any other response will inevitably be interpreted by some as guilt, one way or another.
Even if the chat wasn't faked and what Moon said in it wasn't sarcasm, the guy's no more pedophilic or misogynistic than the average stupid white boy teenager on the internet.
All in all, I think those threads are worth a read for any interested parties or Kiwifar.ms users, since they follow the same logic many of the threads on Kiwifar.ms follow, trusting hearsay and shady sources as fact and extrapolating wild allegations from that lack of evidence. That's not to say that's the entire site, and many of its 'lolcow' threads are more or less just 'ha ha look at this dumb thing this person did on the internet that's dumb', but it does seem to attract users more and more often who get whipped up into this moral frenzy over unfounded allegations.
I think if those users were to read others' smear campaigns of their own site's owner, it might make them more self-aware when they start dragging people through the mud and lobbing pedophilia/sexual offender allegations based on random hearsay they dig up on the internet. The site and its userbase overall is no better or worse than any other site devoted to mocking other people, but it does seem to have an increasing tendency toward this same sort of snap judgement personal-army rallying, which is what I'm saying is made more ironic by the anti-Josh Moon stuff published online.
