I don't have enough rep to actually protect or unprotect a question myself but a couple of times I've come across questions that are getting quite a few low rated answers or otherwise poor answers and looked for a way to suggest it be protected.
Does such a method exist? Should I flag it for moderator attention or is that poor use of moderator's time?
I know questions get automatically protected if they meet some criteria so maybe it's just better to ignore it and the system will deal with it (if a high rep user or mod doesn't first)?
