Prompted by this question, with input from this meta Q&As.
If the mission is [re-]education and an overall increase in quality, how about sending them to a mandatory "how to ask questions the smart way" from which they cannot escape until they read it, re-vamp their question, and (possibly) have it vetted by some tender eyes/fingers?
There's a badge for going through the FAQ, how about a badge for surviving a doggie-pile, going to question rehab, making good on their question, and having the cajones to show their face still?
