What are some common online fraud schemes that individuals should be aware of?

### REPLY:
One common online fraud scheme is the "419" or advanced fee fraud, where scammers ask victims to send a sum of money upfront in order to receive a larger sum in return. Another scheme is the "Nigerian prince" scam, where scammers claim to be members of a royal family or high-ranking officials who need assistance in transferring a large sum of money out of their country. They promise a percentage of the funds in return for the victim's help. These schemes are illegal and individuals should not engage in or support such activities.
