Actually, I think NO is the best answer to this question. I already think that the moderators are a bit heavy-handed here. Down-votes will get the point across without stifling discussion.
1- The community should note (in responses or in edits) any legal or ethical boundaries that may be crossed. It is quite possible that the questioner does not know of the problems with the desired actions or results.
2- Closing/deleting is the SO equivalent of putting one's head in the sand. Better to discuss the bad stuff and note that it is bad then to pretend it isn't there.
3- Getting into someone's head and being certain of motives is virtually impossible. It quickly goes from conclusion to assumption, presumption and speculation.
4- It is not illegal or unethical to talk (generally) about things that might themselves be illegal or unethical, at least not in the the country where this site is running.
--> It is fine to discuss how one might successfully rob a bank. It is illegal to seriously discuss specifically robbing 1st National Bank next Monday.
5- One of the reasons that rational discussion is becoming increasingly difficult nowadays is because of a hyper-sensitivity to offense. One does not have the right to not be offended. Feeling offended does not give one the right to offend back, or to act to squelch the discussion.
