In light of several recent occurrences of people asking for their questions to be deleted after they received answers, I'd like to propose the following addition to our FAQ:
Can I ask career advice questions?
Please be aware that we will not delete your career advice question after you receive answers if you change your mind about having asked it. Think carefully before you post a question full of personal or otherwise sensitive information. If you don't want something to be publicly revealed, consider not posting it on StackExchange.
