Hare Krsna. All glories to His Divine A.C. Bhaktivendanta Swami Prabhupada. The photo above is of ISKCON’s Pepsi/Coca-Cola conscious Paramahamsas, who promote Pepsi/Coca-Cola drinking consciousness. 
Despite all the nonsense inclinations of these bogus Gurus, there are still people who accept that this unauthorized system in ISKCON of bogus Guru worship is bonafide. 
Lecture on SB 7.5.30 — Mauritius, October 2, 1975: Uncontrolled. Our senses are uncontrolled. This morning, while I was walking on the beach, we found so many things, the capsule of the Coca-cola, cigarette butts and so many other things. So what is the necessity of this Coca-cola? You don’t find all these things in our society. We don’t drink Coca-cola. We don’t drink Pepsi-cola. We don’t smoke. So many things which are selling in the market in huge quantity by advertisement, by victimizing the poor customer… But they are called unnecessary things. There is no need of such things.
Letter to Rupanuga — Ahmedabad 29 September, 1975: We do not have to make propaganda, but automatically people will not want. The people are innocent. The rascal leaders say it is primitive to remain on the farm, but to do business in the city and become rogue and rascal, that is advanced. They have dog race, horse race, gambling, coca cola, pepsi cola—all unnecessary. There is no use for it but the business is going on. They take to cigarette and T.V. because they have no good engagement. They are chewing the already chewed. That is nice that the parents are donating. They will donate more and more, because they see here is something good.

Quotes on bogus Gurus and the importance of acceptance of a bonafide Guru

Books : Srimad-Bhagavatam : Canto 5: “The Creative Impetus” : SB 5.15: The Glories of the Descendants of King Priyavrata : SB 5.15.4 : PURPORT :The word anusasmāra is very significant. God consciousness is not imaginary or concocted. The devotee who is pure and advanced realizes God as He is. Mahārāja Pratīha did so, and due to his direct realization of Lord Viṣṇu, he propagated self-realization and became a preacher. A real preacher cannot be bogus; he must first of all realize Lord Viṣṇu as He is. As confirmed in Bhagavad-gītā (4.34), upadekṣyanti te jñānaṁ jñāninas tattva-darśinaḥ: “one who has seen the truth can impart knowledge.” The word tattva-darśī refers to one who has perfectly realized the Supreme Personality of Godhead. Such a person can become a guru and propound Vaiṣṇava philosophy all over the world. The paragon of bona fide preachers and guru is King Pratīha. 
Books : Srimad-Bhagavatam : Canto 6: “Prescribed Duties for Mankind” : SB 6.15: The Saints Narada and Angira Instruct King Citraketu : SB 6.15.16 : PURPORT :This is the way to receive knowledge. One must submit oneself at the lotus feet of great personalities who can actually deliver transcendental knowledge. It is therefore said, tasmād guruṁ prapadyeta jijñāsuḥ śreya uttamam: [SB 11.3.21] “One who is inquisitive to understand the highest goal and benefit of life must approach a bona fide spiritual master and surrender unto him.” Only one who is actually eager to receive knowledge to eradicate the darkness of ignorance is eligible to approach a guru, or spiritual master. The guru should not be approached for material benefits. One should not approach a guru just to cure some disease or receive some miraculous benefit. This is not the way to approach the guru. Tad-vijñānārtham: one should approach the guru to understand the transcendental science of spiritual life. Unfortunately, in this age of Kali there are many bogus gurus who display magic to their disciples, and many foolish disciples want to see such magic for material benefits. These disciples are not interested in pursuing spiritual life to save themselves from the darkness of ignorance.
Books : Teachings of Lord Kapila, the Son of Devahuti : TLK 13: Perfect Knowledge Through Surrender : TLK Vs 28 : PURPORT :To understand these subjects, we should be careful to approach Kṛṣṇa’s representative. We should not approach a bogus guru, who is like a blind man trying to lead other blind men. We must go to one who has open eyes, to one who has seen the Absolute Truth. The Absolute Truth is there, just as the sun is there for everyone to see. The sun does not hide, but a person can try to hide from the sun by closing his door. One must open the door in order to see the sun. Similarly, Kṛṣṇa is there, God is there, and we have to come to Kṛṣṇa and take the lessons of Bhagavad-gītā to learn who and what God is. Rascals will not do this, but will simply manufacture some philosophy or other. There is actually no difficulty because Kṛṣṇa’s instructions are there, and Kṛṣṇa Himself is there. Kṛṣṇa is so kind that He says, “All right, if you cannot understand Me in this way, just see Me in water. Come on, if you do not understand Me in that way, just see Me in the sunshine.” Is this very difficult? There is nothing difficult about it, but we are very obstinate. Māyā is also very strong, and as soon as we try to accept Kṛṣṇa as the Supreme Lord, māyā will whisper in our ear, “No, no. There are many gods. Why are you accepting Kṛṣṇa?” However, the śāstras say, kṛṣṇas tu bhagavān svayam… īśvaraḥ paramaḥ kṛṣṇaḥ [Bs. 5.1]. “Kṛṣṇa is the Supreme Personality of Godhead.” We should take our lessons from the ācāryas and the śāstras. At least in India there are many great ācāryas—Rāmānujācārya, Madhvācārya, Viṣṇusvāmī, and even Śaṅkarācārya and Guru Nanak. All of these have accepted Kṛṣṇa as the Supreme Personality of Godhead. Why, then, should we reject Him? Why should we accept a competitor? We should not simply engage in mental speculation but should accept Kṛṣṇa in full consciousness and be happy. This is made possible by the help of the guru; therefore Devahūti is further questioning her son, Kapiladeva. 
Lectures : Bhagavad-gita Lectures : Bg 2: Lectures : Bhagavad-gita 2.7 — London, August 7, 1973 : 730807BG.LON :So actually āryan samāja means Kṛṣṇa conscious society, International Society for Kṛṣṇa… That is Ārya. Not bogus. So here, Arjuna is explaining, putting himself: “Yes, kārpaṇya-doṣo. Because I am forgetting my duty, therefore upahata-svabhāvaḥ, I am bewildered in my natural propensities.” A kṣatriya should be always active. Whenever there is a war, there is fight, they must be very much enthusiastic. A kṣatriya, if another kṣatriya says: “I want to fight with you,” he, oh, he cannot refuse. “Yes, come one. Fight. Take sword.” Immediately: “Come one” That is kṣatriya. Now he’s refusing to fight. He’s forgetting his duty, kṣatriya duty. Therefore, he’s admitting: Yes, kārpaṇya-doṣa. Kārpaṇya-doṣopahata-svabhāvaḥ [Bg. 2.7]. “My natural duty I am forgetting. Therefore I have become miser. Therefore my…” Now when you become miser, that is a diseased condition. Then what is your duty? Then go to a person who can… Just like when you become diseased, you go to a physician and ask him “What to do, sir? I am now suffering with this disease.” This is your duty. Similarly, when we are perplexed in our duties, or we forget our duties, it is very nice to go to the superior person and ask him what to do. So who can be superior person than Kṛṣṇa? Therefore Arjuna says: pṛcchāmi tvām. “I am asking you. Because it is my duty. I’m now falling in my duty, faulty. So this is not good. So I must ask somebody who is superior to me.” That is the duty. Tad vijñānārthaṁ sa gurum eva abhigacchet [MU 1.2.12]. This is the Vedic duty. Everyone is perplexed. Everyone is suffering in this material world, being perplexed. But he’ll not search out a bona fide guru. No. That is kārpaṇya-doṣa. That is kārpaṇya-doṣa. Here, Arjuna is coming out of the kārpaṇya-doṣa. How? Now he’s asking Kṛṣṇa. Pṛcchāmi tvām. “My dear Kṛṣṇa, You are the most superior person. That I know. You are Kṛṣṇa. So I am perplexed. Actually, I am forgetting my duty. Therefore, I am asking You.” 
Lectures : Bhagavad-gita Lectures : Bg 2: Lectures : Bhagavad-gita 2.13 — Hyderabad, November 19, 1972 : 721119BG.HYD :Similarly, acceptance of spiritual master means representative of God. Of course, he, he must be representative of God. If unfortunately I accept a bogus man as representative of…, that is my misfortune. But actually, acceptance of spiritual master means he’s a bona fide representative of God. Evaṁ paramparā-prāptam imaṁ rājarṣayo viduḥ [Bg. 4.2]. That is stated in the Bhagavad-gītā, you’ll find. That paramparā system, disciplic succession, ācārya. Ācāryavān puruṣo veda. Just like we accept our philosophy, Vaiṣṇava philosophy, or any Indian philosophy, they accept this paramparā, guru-paramparā. They accept it. Sampradāya. Just like we have got sampradā…, Rāmānuja-sampradāya, Madhva-sampradāya. So we have to accept the sampradāya, disciplic succession, to receive real knowledge. So that sampradāya begins from Kṛṣṇa. Kṛṣṇa is the original spiritual master of Lord Brahmā, of Lord Śiva, Nārada, so many other authorities. There are twelve authorities, svayambhur nāradaḥ śambhuḥ [SB 6.3.20]. Svayambhu means Lord Brahmā; Nārada; and Śambhu, Lord Śiva; Kumāra; Kapila; Manu. They are all authorities. So that is the indication of the śāstra, that if you want to understand the transcendental science, the science of God, then tad-vijñānārthaṁ sa gurum eva abhigacchet [MU 1.2.12]. That is the injunction of the Vedas, that if you really interested to learn the transcendental science, you must approach. Abhigacchet. This is vidhilin. Vidhilin. This form of verb is used in Sanskrit grammar when it meant “You must.” You cannot say “I may accept or may not accept.” That will not do. You must accept. Tad, tad-vijñānārthaṁ sa gurum eva abhigacchet, samit-pāṇiḥ śrotriyaṁ brahma-niṣṭham [MU 1.2.12]. These are the injunctions of the Vedas.
