Dirty Rushing

She attended a house all through rush. All the girls told her she was in. On pref night she asked the girls in that sorority if she should intentionally only write down one choice. Two members told her separately to pref their house first but rank 2 sororities and that she had nothing to worry about should would be in their sorority inferring only ranking one would be a problem. She did that and on bid day she did not receive a bid from that house. All week she was honest and vulnerable and they were intentionally or unintentionally lying. The sorority she received a bid from had made a derogatory remark to her so she politely declined their bid. We spoke to panhel today and they said the sorority that dirty rushed her needs to fix the problem and we should call their nationals. If we call their nationals it could create a blackballing issue for her if she decides to rush again. We asked if she could do informal but panhel said no. I truly do not believe that this sorority was malicious in their intent but that something happened with calculations BUT someone needs to fix or correct the mistake.
