Imagine the following situation:
User X has a question. Being a frequent user of SE, he knows that he should always to do some research before asking his question, just in case his question has already been answered.
He finds a question similar to his own. However, he cannot use any of the answers mentioned, because they do not work/are not applicable to his situation/are sub-optimal/<insert other reason here>.
User X then goes and asks his question. In the question body, he specifically mentions what he has tried, and why it doesn't work or why he can't use it.
How to prevent unicorns from eating my daisies?
I love the unicorns who hang out behind my kitchen, but they do tend to eat rather a lot of the daisies. What can I do about this?
Note: I have already tried placing some corn nearby, as mentioned here, but they still choose my daisies over the corn. Strange.
Then a low-rep user comes along and posts an answer, telling the OP to... place a bucket of corn nearby.
You should try placing a bucket of corn beside the daisies. I have heard on the internet that daisies like corn.

Should answers be flagged as NAA if the OP has already specifically stated that they do not want to use the answer's solution? Note that I am not talking about when the OP edits their question after the answer is posted - that is a different situation altogether.
