On the question Why is the center of a torch beam visible even through an opaque body like my finger?, the OP started a bounty stating
I really need this material to answer my entrance examination for BSc. and I can't find this answer anywhere online.
I don't really think we should be answering entrance-exam questions on Physics.SE. However, since the question now has an open bounty on it, I couldn't cast a close vote on it.
I've flagged this for a moderator's attention, but I have two questions that I'd be interested in knowing the community's opinion about:
This is more of a conceptual question (the type of question we "like") than a question about how to work through a specific problem. The rationale for closing homework-like problems is that they're not really useful to future users, whereas more conceptual questions often are. If an OP asks a conceptual question that is based on a homework/exam problem, should it still be closed under this rationale?
Should bountied questions be immune from close votes? Is this something that we can control for our stack only, or is it "baked in" to the whole StackExchange ecosystem?
