So I join Stack Overflow for like almost more than a year like this and mostly I found the question that have been protected by "someone" will be show like the bottom picture. You can directly see that this question is protected.
But just now I visited Information Security Stack Exchange, at first I saw the question get a lot attention and have a high vote but I wonder why this question is not protected. So I just keep scrolling down and see the answer but at the bottom of that page I finally seen the protected label.
(You can see I have a red small rectangle that mark the protected label show at which part.)
So why does Information Security Stack Exchange was different from the other site? Doesn't each site design should be the same?
