I have been asked to do unethical-but-not-illegal things in the past, and in response I (unwittingly) delivered something ethical under the guise of being the requested item. Still dubious ethics, but just between me and the client, not anybody outside. The most common request is to knock off another site. You can hit the save button, or copy code, but what I do is code up a better similar design from scratch. The result is a superior product so everybody is happy, but I would never take code that wasn't open source. I don't even peek at their code during this process!
