I’ve seen several unexpected increases on the order of 10 points over the last couple of weeks. (I don’t remember the exact dates.) My guess was gradual undoing of prior mass-downvoting, but a Mystery Mass Upvoter is certainly another possibility.
[EDITED to add …] A possible variant of the Mystery Mass Upvoter hypothesis: we have a Mystery Small-Mass Upvoter, who is upvoting old posts in Main (maybe because s/he is new here and reading through old material). But that only works if everyone affected has old posts in Main, which I don’t think is the case.
I seem to recall recent instances of a mysterious mass downvoter that produced several threads of people complaining / trying to figure out what could be done.
What if someone is doing the same thing, but with upvotes, to look for bias in community reactions?
Interesting idea. Though I don’t think it’s really indicative of any bad sort of bias if people get angrier about gratuitous downvotes than about gratuitous upvotes.

Hypothesis: we are the subjects of an experiment.

Or they’re just trolling. Whichever.
