If it is wrong, please update it at
translatewiki.net (the key is "noreferences-add-tag"). If you mean you want to adapt it for a specific bot run - you'd have to either adapt the translations file (i18n/noreferences.py) or the bot file itself (noreferences.py:581 ("comment = i18n.twtranslate(self.site, 'noreferences-add-tag')")). There is no command line option for noreferences.py, I'm afraid.
