I have some familiarity with Litvak [Lithuanian] yeshivas which stem from the path of the Gra and the Aderet Eliyahu yeshiva which goes with the actual path of the Gra in Jerusalem.
And then there are study halls on the name of the Gra. All seem very good to me, but I see one advantage to having an actual yeshiva named after the Gra--it tends to exclude cults.
This is the type of institution I would like to see world wide-- Yeshivat HaGra.
But I would also add the study of ethics [Musar].


And I was never in a actual yeshiva of the Gra though I associated with Rav Zilverman for years who is the rosh yeshiva of Aderet Eliyahu.

What we really need to some kind of certification on a yeshiva "cult free" just like they have "preservatives free" labels on food.


The pollution of the Torah world by  cults  has already corroded the credibility real Torah scholars. Yet  those who learn and keep  Torah are not sounding the alarm loudly or moving to fix the problem with appropriate energy. 

 It difficult for those involved in the assessment and promotion of true Torah scholars to discern value from junk.

When something at the core of Torah begins to rot, the smell of corruption quickly spreads to all areas.
