I believe that one tactful way to deal with this is to add a blurb in Panhellenic recruitment promo materials. Something along the lines of:

Each sorority has its own policy regarding new member selection. Those sororities requiring new members to have alumnae recommendations will secure these recommendations on behalf of its new members. Prospective new members are not required to submit recommendations prior to recruitment, but they are accepted. Individual sororities will take these recommendations into consideration in assessing the prospective new member prior to recruitment. Recommendations do not guarantee a bid to membership.

It is recommended that the prospective new member take necessary steps to showcase her recruitment application with the best means at her disposal. This includes but is not limited to: GPA, extracurricular activities and community service, alumnae letters of recommendation and maintaining a ladylike profile in real life and on the internet. Please carefully consider how you portray yourself on websites such as My Space, Facebook, Live Journal, etc.
