A student offered me money to take one of his exams in his place. What should I do?
My advice would be to inform the professor that &quot;students&quot; have contacted you with improper requests such as ...
You were correct to refuse the student, but you may have an obligation to keep them anonymous, as you suggest. That would be true if you have a client relationship with them already, I think.
But the university needs to become aware, if they aren't already, that they need better procedures in place to assure academic integrity. At this time, many are trying (and failing) to get it right and your mail might be a goad to try harder.
You can refuse to help identify the student, but you can certainly make suggestions about improving security.
If your website or other contact methods don't already say it, you might put up a notice of some kind listing what you do when asked to help with cheating.
