Today I noticed this bountied question, which is currently a week old. In my opinion, it’s a homework-like question about QED. But no one has yet voted to close it as homework-like, nor has it been closed by a moderator. So is it OK for me to answer it, or not?
The whole point of putting up a bounty is that the OP expects a complete answer. But homework-like questions aren’t supposed to receive complete answers, or even any answer at all. I don’t want to spend time answering it if my answer is just going to get deleted.
