What are protected questions?
A protected question prevents answers by anonymous and very new users.
Questions should be protected when they are garnering lots of views and newbies are adding "me too!", "thanks!" and possibly even spam non-answers.
Which questions can be protected?
Any question, even a deleted question, can be protected and unprotected, subject to the following restrictions:
- The question must be at least a day old
- A user can unprotect a question protected by him or herself, but not one that has been protected by someone else
