I understand it's possible to check who downvoted comments? It was probably a generically-named sockpupuppet, I guess, but still.
I understand that there is a limit on downvoting -- it doesn't cost karma, but it's only possible up to the limit of one's karma, or something like that. If so, a sockpuppet wouldn't have enough karma. It must have been an account with a real presence here, either bingeing on OCD or using an automated script.

I think it's much higher than that, like 4 times one's karma or even more so (which I find rather ludicrously high). Something like that would mean that a mere 300 karma (extremely easy to achieve by saying nothing actually worthwhile) would suffice to downvote another person 1200 times..
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
