Tell your advisors that their "invite everyone back" strategy is hurting rather than helping -if they don't believe you, show them greeek rank and other sites where people talk about such things. Advisors who think this strategy works are oftentimes from chapters that never had to worry about it and were super selective. If they won't listen to you, go over their heads to whoever is next highest up in the chain of command. Be sure to back up your complaints with facts (since they started making you invite everyone, your return rates have dropped 25%, etc.).

You also might want to pass a bylaw (for now you can strongly suggest) that every sister must be involved in one campus activity outside of the sorority. No, jobs don't count. No woman wants to join a chapter whose members do sorority and nothing else - it contributes to the "snobby" stereotype.
