Shulchan Aruch, Orach Chaim 690:16 says
One must say "Accursed is Haman, blessed is Mordechai, accursed is Zeresh, blessed is Esther, accursed are all who hate HaShem, blessed are all who believe in HaShem," and one must say "And also Charvonah should be remembered for good."
Other editions of the Shulchan Aruch have different versions of the bolded phrases. However, in many congregations, and in the ArtScroll siddurim, these words are completely omitted. Why?
