Today I was going trough some reviews on Stack Overflow on the Low Quality Posts list. I flagged this answer as "Not An Answer" as "This does not provide an answer to the question. To critique or request clarification from an author, leave a comment below their post". Then I got an, at least, unusual and rude answer from the answerer:
@Yaroslav Are you kidding me? Don't tell me how to use this site, son, I have been here much longer than you
I flagged the comment as rude.
Then, with no apparent reason, just few minutes after receiving this comment, I got two downvotes on a couple of my answers, already verified with the OP in question, without any comments on how to improve my answer or what was wrong so I could correct it.
So, apparently as he has +20k I can not flag one of his answers? Just because someone has ten times my reputation implies that he can't be wrong once a while? And by the way, the accepted answer with three upvotes is from a user with 496 reputation.
It is not the first time I see these kind of actions. It is not common, but it happens. It's there a way to prevent/avoid this? If I see a high rep user with an incomplete/incorrect answer, should I flag it or not? I will flag it of course, whenever I see it. I guess it is something already known on all Stack Exchange sites, but nevertheless I don't see the point on just downvoting other answers just for vengeance.
EDIT
It happened for two more answers and with the same pattern. This one got three downvotes in half an hour, as it was indeed not correct, I deleted it. This other answer is suffering the same issue. And it is weird, at the end, as my answer was correct in this particular case.
