One of my questions is protected. This is what I see when I open it:
That is, I see the banner:
Highly active question. You have enough reputation to answer this question. The reputation requirement helps protect this question from spam and non-answer activity. Learn more.
I don't think it makes much sense to indicate to me, the OP, that I have enough reputation to answer my own question. While it is important to notify a OP that they cannot answer it, I think that indicating that they can does not add value.
Once you've seen this banner several times, it would be useful allowing to dismiss it or leave it on the footer. It takes important space when it is no longer relevant.
