That is very creepy. I'm so glad you figured it out. The internet and Facebook are not the only way people get information about you though. It's just the way it is now. I shred everything with my name or address on it before it goes in the trash- why make it any easier for the sleazebags?
I don't post my location on any boards but if someone wants your information it can be found. Yuck! I hate the feeling that this gives me but I sure don't want to hide my head in the sand. Let's make sure we keep each other up to date on any scams or risks we know about. It can't hurt.
