I posted this answer here: https://math.stackexchange.com/a/1121698/205062
My answer was commented upon by someone who misunderstood it but that comment (the second comment) has attracted two upvotes. I find it very rude to misconstrue my post and then pour further salt in the wounds by upvoting what I did not intend!!!
I think this kind of action should be not allowed. It is not conducive to good discussion to have dishonest misrepresentation (I don't blame the commenter but the upvoters).
