It is interesting to note that approximately the same time the Tropper tapes were being recorded that Tropper had Rav Reuven Feinstein write a haskoma for his activities in EJF

My Honorable Friends, Rabbis of the Eternal Jewish Family Organization,
I would like to take this opportunity to reiterate and clarify my previous stated opinion that all of the activity of this organization strictly adheres to the Torah's laws as transmitted by both the leading halacha deciders of our time (may they live and be well) as well as those of blessed memory.
The Eternal Jewish Family has my full support, as at the helm of the organization is a halacha committee made up of Torah scholars endowed with a strong fear of heaven who are admirable in both thought and action.
The directors of EJF are of the elite few of our generation who follow the directives of today's Torah leaders. They are willing to listen to their constructive criticism, and even adjust the organization's activities or strategies when instructed.
The mixed seminars for couples that EJF runs follow the strict guidelines and Torah decisions of the previous generation's Torah luminaries, as well as today's leading Rabbinic authorities, our master HaGaon Rabbi Yosef Shalom Elyashiv shlit"a and HaGaon Rabbi Shmuel Vosner shlit"a and our master HaGaon Rabbi Yosef.
May you be blessed to continue sanctifying the great Name of Hashem and strengthening the Glory of Heaven until the final redemption.
Signed in blessing and true friendship,
