I just noticed that this answer received an impossible number of upvotes over the past hour or so.
I've seen popular answers before, but this just doesn't seem likely because:
The question was answered exactly one year ago today, which just seems like too much of a coincidence.
The topic has had no recent activity other than a stray vote every month or so.
Over 80 votes have been added at a rate of pretty much 2 vote per minute according to my daily rep breakdown.
Has anyone seen anything like this before? I might have thought it was a client-side problem, but I'm getting the badges for it and everything.
