I flagged an answer with the option very low quality. According to this option description:
This answer has severe formatting or content problems.
As far as I understand, the word content here means the technical side of the answer - the actual information given in the answer, and if it's technically incorrect, then the answer has severe content problems.
But I've got a flag declined with the reason flags should not be used to indicate technical inaccuracies, or an altogether wrong answer. This reason seems to conflict with the very low quality option description.
I'm not going to argue with this decision. I just want to understand the policy behind it in order to flag properly in future.
Question: when is the question considered to have severe content problems?
