The Russian Mafia is a group of bad people who work together to do bad things like stealing, hurting others, and breaking the law. They are organized into groups called gangs that have leaders who make rules and control their members.
These gang members can join for different reasons, but usually they want to make money, have power, or fit in with others who are like them. They are also very secretive and try to keep their activities hidden from police or law enforcement officials.
Some of the ways they make money include selling drugs or weapons, running illegal businesses like gambling or prostitution, and even extortion or blackmail.
Sometimes, these groups can even be connected to important people in government or business, which makes it harder for law enforcement officials to stop them.
Overall, the Russian Mafia is a dangerous and illegal organization that operates in secret to do bad things, and it's important to stay away from them and tell the police if you ever see or hear about any illegal activity.
