### REPLY:
The most common types of online fraud schemes include phishing scams, where attackers impersonate legitimate entities to deceive individuals into revealing their personal information or login credentials. Another common scheme is credit card fraud, where stolen credit card details are used to make unauthorized transactions. Identity theft is also prevalent, where personal information is stolen to commit fraudulent activities. Additionally, investment scams and pyramid schemes lure individuals with false promises of high returns, only to swindle their money.
