Even though it is very easy to track someones location from their IP, most people do not know that. They feel that their privacy is being violated when someone "reveal" in which nation/city they live and which ISP they use.

You're not doing anyone any favours by contributing to such an illusion. In fact, you may actually be putting them in real danger.
