Some common online fraud techniques used by scammers include phishing, identity theft, advance-fee fraud, and pyramid schemes. Phishing involves tricking individuals into revealing their personal information through deceptive emails or websites. Identity theft occurs when someone steals another person's personal information for financial gain. Advance-fee fraud involves convincing victims to pay an upfront fee with the promise of a larger reward. Pyramid schemes involve recruiting individuals to invest money with the promise of high returns, which are paid from the investments of new recruits.
