Ok so a few months ago Protected Questions were added to the system. However, to date the only one I've come across is the example question on Meta. Are any questions being made protected? I remember flagging a few questions as possible candidates for the feature(ones with a constant stream of "thanks" and "me too" answers) but nothing came of it.
Is the protected question feature just something put up on the shelf for a rainy day or are moderators actively using this feature?
