Most unethical? Probably pre checking one of those cookie policy checkboxes or what not. Wasn't too happy about that, especially when the software used removed the feature before for exactly the reason you may expect. I also previously used a mod to read personal messages on a forum once, though that's one of those things which is heavily, heavily debated about on community management sites, with about half the audience saying its an unethical breach of privacy and the other half saying either that it's their site and property deal with it or that it's a good way to stop poaching and abusers. But that one wasn't exactly coded by myself, so eh, it's an edge case for this question. So probably a tie between those two, depending on what you count by 'as a programmer'. Fortunately, everything else I've been asked to do in my career has been pretty normal/ethical.
