I flagged as "very low quality" a post. The flag tooltip says
This answer has severe formatting or content problems. This answer is unlikely to be salvageable through editing, and might need to be removed.
The refusal says
flags should not be used to indicate technical inaccuracies, or an altogether wrong answer
My point is that the flag I raised was not raised for technical inaccuracies or because the answer was wrong, but because, like a mod said in the comments to the answer I flagged
Politics.SE is a question and answer community, not a discussion forum. We expect people to back up statements with sources.
and the answer was lacking sources and was barely answering the question, that to me falls squarely under the "severe formatting or content problems" of the tooltip above.
So, please, can someone explain when/how should this flag be used?
