Oh, sure, but it would take a while. The system is not Fort Knox. If someone wants to find one of the members that badly, then there are actually easier ways, outside of the system.

If we decide that it is a concern, I already know how I'd deal with it. I would add a "governor," to slow the process down. Depending on how the location is updated, that could be enough to render it worthless. People can't even see the "fuzzed" locations, unless they are registered members of the community. The locator would have to go through a registered account, and those don't come too easily.

However, if someone is that concerned, they would either hide their location entirely, or not join the community. The app is all about people finding each other.
