pāṇḍitye cāpalaḿ vacaḥ
lingam- the external symbol; eva — merely; āśrama-khyātau — in knowing a person's spiritual order; anyonya — mutual; āpatti — of exchange; kāraṇam — the cause;avṛttyā — by lack of livelihood; nyāya — in credibility; daurbalyam — the weakness; pāṇḍitye — in scholarship; cāpalam — tricky; vacaḥ — words
A person's spiritual position will be ascertained merely according to external symbols, and on that same basis people will change from one spiritual order to the next. A person's propriety will be seriously questioned if he does not earn a good living. And one who is very clever at juggling words will be considered a learned scholar. SB 12.2.4

The epidemic of bogus gurus, swamis, priests and so forth is explicitly described here Sb 12.3.38
Srila Prabhupada explains about the position of bogus gurus
Jayatīrtha: Yesterday Nitāi found a quote from the Purāṇas that says, “There are many gurus who will take away your money, but rare is the one who will take away your miseries.
Srila Prabhupāda: Guravo bahavaḥ santi vittāpahārakaḥ
Devotee: Yes, right.
Srila Prabhupada: guravo bahavaḥ santi vittāpahārakaḥ taṁ tu guruṁ na paśyāmi śiṣya-santā-paharakah
There are many gurus. They are very expert in plundering disciples’ money, but it is very difficult to find out a guru who can take out all the anxieties of the disciple.” Śiṣya santa-pahārakāḥ. Guru is meant for taking away the santāpa. Saṁsāra-dāvānala-līḍha-loka-trāṇāya kārunya-ghanāghanatvam **. “The śiṣya will be peaceful”—objective of life—that is the business of guru, not to take away his money
Morning Walk Conversation with His Divine Grace A. C. Bhaktivedanta Swami Prabhupāda February 4, 1975
Acyutānanda:: If a man says, “I am giving you this donation because it is a spiritual organization,” but if the money is misused, does that man benefit.
Srila Prabhupāda: If money is misused, then both of them become implicated. If it is not used for Kṛṣṇa, then both of them becomes under the laws of karma
Srila Prabhupad warns about so-called acaryas of the age of kali
vicāra karena, lokera kaiche hita haya
Seeing the activities of the world, the Ācārya felt compassion and began to ponder how He could act for the people’s.
This sort of serious interest in the welfare of the public makes one a bona fide ācārya. An ācārya does not exploit his followers. Since the ācārya is a confidential servitor of the Lord, his heart is always full of compassion for humanity in its suffering. He knows that all suffering is due to the absence of devotional service to the Lord, and therefore he always tries to find ways to change people’s activities, making them favorable for the attainment of devotion. That is the qualification of an ācārya. Although Śrī Advaita Prabhu Himself was powerful enough to do the work, as a submissive servitor He thought that without the personal appearance of the Lord, no one could improve the fallen condition of society…
The so-called ācāryas of the Age of Kali are more concerned with exploiting the resources of their followers than mitigating their miseries; but Śrī Advaita Prabhu, as an ideal ācārya, was concerned with improving the condition of the world situation
