One cool thing about having a common first and last name combo... I don't think that anyone can find me by searching for Matt Hall.
I'm pretty sure that it is much easier to find out who someone is by their email address. I think everyone's email address is public here too right?
Plus, there are bigger privacy concerns then net 54 on the internet.
If you haven't seen this website, type you name in search, see what they have, and opt out:
