facebook privacy help?

[Keyboard Cowboy]

This is why they call it stalkbook

That being said -- you can set the privacy settings to block strangers from seeing personal information about you, HOWEVER if you post a comment on someone else's page, and their Wall security is set to public, then everyone will see what you said to them.

In this case there's nothing you can do, except ask your friends to apply the same sort of security measures that you apply to your account. You can do this by warning them about the dangers etc but if they are young, then they simply might not care because they are ignorant of the dangers.

Anyway, good luck and be careful out there!
