It's not a big problem but we regularly get questions about the various possibly commercial uses of photos of people and places without a legal agreement in place to which the answer can almost always be summarised as 'every country is different so check with your local lawyer' and thus should be closed as 'primarily opinion based'.
Photos of people on an ad supported website Is it legal to use a photo taken on private property Can I publish photos taken in public legally
I usually point them at my old question: When Do You Need a Model Release but that has problems in that it is essentially an open ended list question and thus equally poor.
Even this otherwise excellent question is still essentially a 'list' question.
Is it worth adding something to the FAQ (or some sort of wiki item) about this sort of question and pointing askers to it when closing?
