This deleted question (10k+ users only) is a student who just copied exam questions and wanted help, and admitted it in the comments to me before deleting the question. I would like this question to be undeleted, closed and protected, so they can be caught. If the student used a university email, I would hope the mods could find time to drop a line to their department, though I understand it's not their job. I do wonder if Math.SE has had any similar cases...
