I understand the fundamental purpose of ranking questions - in short, ranking them up says to readers the question was good/important, and down that it was a bad question or not fitting for the stack's purpose. I agree with it wholly.
There seem to be circumstances where users downvote aggressively or in retaliation to questions/comments they dislike or don't understand.
My question is simply, what can/should an OP do when they feel they are subject to this kind of behavior?
Forgive me for using my own example, this one in particular is mild but should get the point across:
The question is clear, and the comments and downvotes appeared only after replies in comment asking people to read the referenced article and understand what was being asked.
