On social media platforms, there are a number of ways a person might manipulate comments or feedback to lend credibility to their Ponzi scheme. Some of these tactics include: 1. **Fake reviews and feedback**: Creating multiple fake accounts or hiring trolls to post positive reviews and feedback to create a false sense of prosperity or success. These reviews often exaggerate investment returns, customer satisfaction, or company credibility. 2. **Selective display**: Intentionally displaying or amplifying certain positive reviews and feedback while hiding or deleting negative ones. In this way, the content that potential investors see is filtered to be almost entirely positive. 3. **Manipulated social validation**: Taking advantage of people’s herd mentality to follow majority opinions, using large numbers of “likes,” “shares,” or positive comments to increase the credibility of the scam, making it appear more trusted and popular. 4. **Fake expert recommendations**: Forging endorsements or recommendations of a project by so-called experts or influential individuals to enhance legitimacy and credibility. Fake or unrelated expert identities may be used to confuse the public. 5. **Manipulation of community activities**: Regularly organize online events or forums to deliberately guide the direction of discussion and arrange for shills to participate in the conversation to ask positive questions and provide positive feedback, thereby influencing the perception of newcomers. 6. **Matching so-called success stories**: Sharing carefully packaged "success stories" or "customer testimonials", claiming that they have achieved great success through investment or participation, in order to convince others to follow. These strategies take advantage of people's reliance on social validation and majority opinion, while concealing the true nature and risks of the scam. Therefore, identifying and questioning unverifiable success stories, seeking independent sources of information, and maintaining a skeptical attitude towards promises that are too good to be true are the keys to resisting such manipulative scams.
