For the record, I'm not /u/hone. If you're bored enough to trawl through my comment history, you'll see I've never called anybody a shill. For all my reasoning faults, it's not my style; I'd talk about a "conflict of interest" or something. The only way this could be me is if I were trying to discredit anti-Semitism by associating it with such inanity. (But I don't really think it needs my help with that.) Or, possibly, try discredit anti-Israel sentiment by associating it with anti-Semitism? But that's out of character, too, because I don't really care enough about the geopolitics of the Levant to (badly) employ dark-side epistemology.

Plus, you know, I don't use alts. (But you don't have any way of verifying that.)

I think this user is being honest at simulacrum level 2 – that is, their words are lies, but their sentiment isn't deception; you can take their slander of you as an honest "I don't like /u/JasonCarswell". I think /u/hone is probably an alt, but perhaps not of the same person; there are a lot of people who talk like that and I struggle to tell the difference between them.

A tip: since you identified a connection that wasn't there, be slightly more wary to make connections in future – though not much more wary, because this is only one failure, and you'd be silly to aim for a 0% false positive rate. Perhaps write them down, or use something like PredictionBook to help calibrate your certainty.
