I don't agree that mis-leading answers should be discouraged.
The fact is, many times monks at different levels give different answers (and they are very honest), they think that they are right. Ultimately some guru provides the correct answer and the question ends. This is how any discussion goes in real-life also.
We should encourage monks to talk, discuss and to be BOLD. Even Wikipedia (a Free web-encyclopedia) asks its members to ‘Be Bold’, it allows wrong information (There are many reviewers who correct the wrong information).
Also I believe that Monks who posts questions are wise enough to test the solutions, before implementing it in their projects
