I agree with this, but I think it's worth noting that the prompt here was someone making a specific claim. One doesn't need to believe they have made no mistakes to be certain they've never made a particular mistake, and there's significantly less room for differences in interpretation (though that's not to say there's none).
If users could look at the actual record, their perennial sob story of perfectly reasonable behavior struck down by bullying censors would evaporate. So they make new accounts and post statements designed to be unanswerable.
I interpreted that as dang attributing essentially every complaint to malice, and simultaneously dismissing all other explanations.
A misleading summary, since you're the one who introduced the idea of "malice" and "fraud". Dan's claim admits to HN users who believe they've been hellbanned for criticizing YC companies. Yours doesn't.
