I don't see why Mitch would be worried if people knew his real name and address, when he lives in Dubai. It's not like someone is going to get on a plane and go there. Now if his work info is online, that would be a concern.
Every now and then, I'll type my name into google and see what comes up. There's a few TW references that link to my handle, but my job info is not there, at least in the 1st searches. That's why I'm not on LinkedIn. If you put your info on that site, it ends up on Google and a few 3rd party web sites.
