sockpuppet accounts to downvote people he didn’t like
I’ve been mass-downvoted quite a bit by Eugine and I don’t recall ever seeing any comment of mine downvoted more than once. If he’s using sockpuppets, it’s not so much “to downvote people” but either (1) to hide his mass-downvoting by splitting it among socks or (2) to upvote his own comments (whose karma trajectory over time is often rather peculiar).

Sockpuppets are for upvoting, not downvoting, because downvoting requires karma and upvoting doesn’t.
Also, whereas as gjm noticed hardly any comments have more than one “anomalous” downvote, plenty of comments have like half a dozen anomalous upvotes.
Traditionally he posted quotes in Rationality Quotes threads to farm karma he could use for the downvotes. Maybe he got tired of doing that.
