Two days ago I reported this comment as unfriendly/unkind:
Whoever downvoted my question, you really are a weird person. Downvoting with a comment as WHY downvoted makes sense so that I can at least fix the question or something. But anyways, good luck to you as a developer who only knows to find faults and no solutions.
My reasoning is that it starts off by calling the downvoter "really a weird person", which is not something you should call anyone in a professional environment; and is followed by unwarranted and excessively snarky remarks about their modus operandi as a user on Stack Overflow and as a developer in general.
However, my flag was declined, with the comment removed anyway. Why was that? Was this a mistake from the moderator? Why should we not advert people not to make inappropriate remarks such as these in the future?
