I ran across this site Nextdoor.com, it is another social media site with one difference. “Nextdoor is the private social network for you, your neighbors and your community. It's the easiest way for you and your neighbors to talk online and make all of your lives better in the real world.” The idea is that only people in your real neighborhood can join. Out of curiosity I started looking around the demo site and started to think, this sounds like a terrible idea.
However, in my opinion this starts to go wrong very fast. A quick Google of site: nextdoor.com already starts to produce some interesting results. The first and second page reports results such as the West Briar, Pointe Marin, Covie Hill and Bent Creek. Clicking these links will take you to a login page where you can get a little more information about the neighborhood, such as the city, state and an outlined map of the neighborhood.
Okay, so what’s the risk? First the “bad guys” already know the city, state and the neighborhood. Another quick Google search results in finding an invite page where you enter your address and thanks to the mini map and some more Google it is easy to find an address within the outline.
