Thank you.
I could ban that account. Thoughts about whether that would be a good idea?
+1 to the anon who used the "username2" account to post the parent comment. IIRC, there was an original "username" account, the use of which of collectively discontinued several months ago because its value to the community was co-opted by abusive anonymous users logging into it. I would hate to see that happen a second time, to "username2". If it were to happen a second time, that would disincentivize necessary, honest, and respectful use of the anonymous account.

I've gotten sufficient evidence from support that voiceofra has been doing retributive downvoting. I've banned them without prior notice because I'm not giving them more chances to downvote.
I'm thinking of something like not letting anyone give more than 5 downvotes/week for content which is more than a month old. The numbers and the time period are tentative-- this isn't my ideal rule. This is probably technically possible. However, my impression is that highly specific rules like that are an invitation to gaming the rules.
I would rather just make spiteful down-voting impossible (or maybe make it expensive) rather than trying to find out who's doing it. Admittedly, putting up barriers to downvoting for past comments doesn't solve the problem of people who down-vote everything, but at least people who downvote current material are easier to notice.
Any thoughts about technical solutions to excessive down-voting of past material?
