I was clearing the "low quality posts" queue, and I marked an answer as "Looks OK". The system then told me that this was just an audit and I failed the test. I believe I was right to accept it, and so I'm asking for guidance here.
The question was Calculus book suggestion, and the answer (now deleted), was:
The question explicitly asks for a good calculus book for beginners. The answer provides a good calculus book for beginners, and even gives a link to the book. As far as I'm concerned this is not
- spam,
- offensive,
- off-topic,
- abusive.
Then why is it marked as such?
