The term 'flamboyant deceivers' is a reference to CHARLATANS, which are people who make false claims or promises in order to deceive others. They often use flamboyant language and behavior to draw attention to themselves and their schemes. CHARLATANS have been around since ancient times and can be found in many different cultures. They often use their charisma and persuasive skills to convince people to invest in their schemes, which often turn out to be fraudulent.
