The internet would be a lot poorer, if all users had to be identified. I really appreciate it when people tell their personal stories and talk about how they have overcome crises. Anonymity empowers people to help others by sharing life lessons. Those same life lessons would be very harmful for the reputation of the internet user, if they had to be posted with the user's real name.

Not everyone has a life that is all sunshine. Not every use of anonymity is criminal or unethical.
