A scam is a deceptive scheme designed to con people out of their money or personal information. Scammers often use tricks or false promises to lure victims, making it seem like they are offering something valuable, such as a prize, investment opportunity, or job offer. These schemes can take many forms, including phone calls, emails, or online advertisements. Common types of scams include phishing, where fraudsters impersonate legitimate organizations to steal sensitive data, and Ponzi schemes, which promise high returns to investors but rely on new participants' money to pay earlier investors. Awareness and caution are essential to avoid falling victim to these fraudulent activities.
