The map only shows the town/township, as you said many have that listed here. What's more the dot on the map doesn't pinpoint an exact lacation, such as when using mapquest. The map also doesn't zoom in close enough to see streets and such. But I guess you probably already knew that.
Sites like "My Space" are much more dangerous, people love to post photos of themselves, blab on and on giving out personal information, post where they work, what they drive, do everything except give out their street address and SS number. It's a rapist/murderer's haven.
My daughter has her page set to private, she has to add you as a friend before you can view her profile. Some *censored* in Australia was sending her messages recently.
With the Internet if somebody wants to find you badly enough I suppose almost any shlub with half a brain could do it.
That's why I am thankful for the 2nd Amendment!
