most people do not put their actual locations down because many websites have rules against people posting personal identify able information that can leave the poster and the site creators, admins and so forth open to violating their state laws for stalking and internet usage.

many dont put their actual locations because theygrew up in the computer age where computers became a normal thing in schools so schools had to teach internet safety such as teaching students how to not fill in registrations and profiles and posts with personally idenify able information.

many dont put their actual locations because they had computer safety parents who taught them not to leave their self open to cyber criminals.

directly related to me and my family .. my children learn about computer/ online safety at home and in school & my wife and I practice computer and online safety of not disclosing our actual locations.

as part of my children's computer safety courses in school the police department gives educational talks, meet and greets and so on where they discuss internet safety like how to not disclose personal information like location.

there are also many great you tube and tv shows and cable shows that teach about internet safety. local libraries also have sections / departments that will work with anyone that wants to learn how to protect their self online from stalkers and such.
