2@codekaizer I generally would not downvote a harmless dupe just for being a dupe, but when it is upvoted for no reason, I understand people might want to balance it slightly, only to make sure we are sending right signals to other users. Also this is not a well-asked question even if it would not be a dupe. – SergeyA May 11 '18 at 07:49

2The [policy](https://meta.stackoverflow.com/questions/361399/is-it-fine-to-vote-up-down-to-compensate-the-votes-of-others) is "don't vote based on the current score". Although I do think that the voting is weird, unless a voting ring is involved there should be no problem. – user202729 May 11 '18 at 07:51

@SergeyA This question is exactly what I typed in google and the answer exactly provided me with what I needed. Simple solution for simple problem, which I am too lazy to investigate further - works for me. – Petr Apr 05 '19 at 13:40
