I recently flagged this post as "low quality". As you can see (if you have enough rep), it has been deleted by three other users. In addition, from the review history I see that noone disagreed:
From this I understand that my flag has been useful, but on my profile I read this:
declined - flags should not be used to indicate technical inaccuracies, or an altogether wrong answer
Why is that?
EDIT - Additional data:
I have raised the "low quality" flag 26 times, 25 of which were "helpful".
If I try to flag any 0-score-answer I am presented with this choice:
This set of choices is in blatant opposition to the message I received in the reject message: there is a flag reason for technical inaccuracies/wrong answers or "severe content problems" as the prompt puts it. It's the SE system that tells me that this is an option.
I understand that somewhere there has been a misunderstanding or a mistake has been made. I asked this question in the hope to identify the cause and avoid it in the future.
My understanding of the system is that by raising that flag the post is placed in the "low quality" review queue, if it was not already been automatically placed there by the system (and that this is the only way a user can place a post in that queue).
