"Deprecated" in Flagged Revisions

You probably see them in Turkish, because your interface language is Turkish. I see them in Hebrew, which is my interface language.

Your answer brings me back to my question: Is it the same as "rejected" or is it something else?

No no, I see them in both languages: English and Turkish. I even check German time to time in order to make sure.

My choice would be "rejected/rejection" or "disapproved/disapproval" rather than the one used in a typical IT context.
