Purport: 

Commenting on the word parama-vaiṣṇava, Śrīla Bhaktivinoda Ṭhākura says that anyone who desires to merge into the existence of the Lord cannot be a pure Vaiṣṇava, but because Rāmadāsa Viśvāsa was a great devotee of Lord Rāmacandra, he was almost a Vaiṣṇava. In those days, no one could distinguish between a pure Vaiṣṇava and a pseudo Vaiṣṇava. Therefore Rāmadāsa Viśvāsa was known as a Vaiṣṇava because he worshiped Lord Rāmacandra.
