I have over 15 reputation and have been given the [flagging privilege](https://workplace.stackexchange.com/help/privileges/flag-posts).

I understand the guidelines for [spam and offensive flags](https://meta.stackexchange.com/a/58035), but it seems The Workplace has [different standards for 'very low quality' and 'not an answer' flags](https://workplace.meta.stackexchange.com/questions/2402/are-we-using-naa-and-vlq-flags-correctly), when/how should I use them?
