You can't. Men and women should maintain a relationship of equality, respect and mutual understanding when interacting with each other. Men can't make money from women by chatting and making friends, which is not only immoral, but also may involve illegal activities. This kind of behavior is usually called "fraud", which is an act of defrauding other people's property by deception, and it is an illegal and criminal act. If someone fabricates identity or facts to defraud women's property in the name of chatting and making friends, they should call the police immediately after being discovered and let relevant institutions intervene in the investigation.
