I came across an answer to this question whilst carrying out reviews. I'm wondering what the best way to handle this kind of situation is as I'm sure others have come across it too.
The question if asked today would be flagged as not constructive and closed rather quickly. It was posted in April 2009 however when the rules were slightly more relaxed I believe.
I think maybe it should be locked rather than closed but I am not sure on this. Looking for some guidance. It seems to have been useful with over 1800 views and 12 favourites.
Also, is there some message that can be given to the user that posted the new answer to not post answers on old questions that aren't constructive? I suppose if the question was locked, this wouldn't have been an issue though :)
