Possible Duplicates:
Technically valid answers that raise questions of morality
How far should we go in judging question ethics?
What does everyone think about a downvote for a question considered "unethical"? Who's that judge for that? I guess a question should be judged strictly on technical merit.
Examples:
https://stackoverflow.com/questions/2598099/how-to-know-email-address-of-sender
Stack Smashing attempt giving segfault (this one initially got downvoted)
And also another question I had about writing social networking bots, but never posted because I found a solution elsewhere.
So what should be the policy on this kind of questions?
