Can someone help me clearing up with what should be flagged and what should not?

Question

question 1: Ok, so lets take this question as an example. the BA is incorrect now, but should it be flagged? its a really old question...
question 2: I have heard some people say an answer should be flagged if its against the rules while someone says if the answer is incorrect. what is right?

Answer 1

So, the real thing is:

For questions:

• Flag it if the question is against the rules.

• Vote it down if the question is bad in another way, for example terrible spelling, impossible to understand etc.
  For answers:

• Flag it if the answer is inappropriate in some way or breaks the rules (e.g. it's not an actual answer and should be a comment).

• Vote down if the answer is incorrect. (Side note: on the RMT section only vote down answers if they're really bad, because some answers may not be great but still not technically wrong.)

For comments:

• They should be flagged if they are rude or insulting for no reason. For example if an answer is bad you might downvote it and post a polite comment saying that it's wrong. But saying "you're dumb" or stuff like that is not welcome here and should be flagged.
• Also comments should be reasonably on-topic relating to the question or answer. A random comment like "hey what's your favourite Pokemon" should be taken to the chat.

I heard the word polite, that's my queue

Ok, so an answer should only be flagged if it break the rules and not if its incorrect. thanks
