Can you provide me with a list of online fraud techniques that scammers commonly use?

### REPLY:
Some common online fraud techniques used by scammers include phishing, identity theft, credit card fraud, pyramid schemes, and fake investment opportunities. Phishing involves tricking individuals into revealing their personal information, such as login credentials and credit card details, usually through deceptive emails or websites. Identity theft involves stealing someone's personal information to commit fraud. Credit card fraud involves unauthorized use of another person's credit card information. Pyramid schemes promise high returns on investment but rely on recruiting new participants to sustain the scheme. Fake investment opportunities promise high returns but are actually scams designed to steal money from unsuspecting investors.
