Who Has Removed Preferential Treatment for Legacies?

[ASTalumna06]

At this point, which organizations still have preferential treatment for legacies during recruitment? From what I've found, the following still have theirs intact (or there was no announcement of a change of policy easily found):

Alpha Delta Pi
Alpha Epsilon Phi
Alpha Sigma Tau
Chi Omega
Delta Phi Epsilon
Delta Zeta
Kappa Delta
Sigma Delta Tau
Theta Phi Alpha
Zeta Tau Alpha

And these orgs have clearly eliminated their policy:

Alpha Chi Omega
Alpha Gamma Delta
Alpha Omicron Pi
Alpha Phi
Alpha Sigma Alpha
Alpha Xi Delta
Delta Delta Delta
Delta Gamma
Gamma Phi Beta
Kappa Alpha Theta
Kappa Kappa Gamma
Phi Mu
Phi Sigma Sigma
Pi Beta Phi
Sigma Kappa
Sigma Sigma Sigma

If any part of this is incorrect, please feel free to clarify.
