Do Vaishnava Acharyas Like Lord Brahma Fall Down?

In 1976, “Nitai dasa” said that vaishnava acharyas may fall down. He cited the alleged example of Lord Brahma’s fall down (which took place before he had heard the Bhagavatam Verses), and which is not appropriate to cite as an excuse for bogus cheaters posing as acharyas in the first place. Anyway, Srila Prabhupada said Nitai is a rascal, poisonous, and he banned Nitai from ISKCON. Srila Prabhupada says in his “who is that rascal?” conversation, that those who think the acharyas do not have to be a pure devotees are rascals. This would seem to indicate many prominent current leaders of both ISKCON and the Gaudiya Matha?
