I have gotten a few "bursts of downvotes" in the past few weeks that look something like this in my inbox.
I would assume the site would automatically catch this and reverse it, as happens with "bursts of upvotes" (which I have had happen only once) that look like this.
I am wondering: what is it that triggers or doesn't trigger the automatic reverse voting?
From the few examples that pertain to myself, my best guess is that it's four or more votes in either direction that trigger it.
It looks like the mod Xander has looked into this before, but I didn't see any of the reversals he was speaking of. I suppose I don't really know what "raise a flag" means either.
Sorry if I have asked too many questions. Just trying to understand how this works.
