What is an example of unethical marketing of word of mouth company?

An example of unethical marketing in a Word-of-mouth company could be when a business pays individuals to promote their products on social media without disclosing that they are compensated. This practice, often referred to as "astroturfing," misleads consumers into believing that the endorsements are genuine and organic, thereby undermining trust and transparency. Such tactics can distort consumer perceptions and violate advertising regulations, ultimately harming the reputation of both the company and the influencer involved.
