Can we add a close reason that conveys the idea "This question should be asked of a legal professional."?
Perhaps set up as:
This question is asking for legal advice. Questions about the law are welcome, but questions asking for legal advice need to discussed with a legal professional.
We would need to add corresponding information to the tour so that notice is given that this is a reason for questions to be closed.
My hope is that this would address concerns about unlicensed practice of law issues.
