While I won't claim to be untrackable I have always avoided throwing my real name around the nets and have used a pseudonym as much as I could. I also removed myself from as many databases that allowed me to when I first discovered myself in online records.
I'm not DUmmie-stupid enough to sign my name at the end of posts to try and up my street cred with a bunch of morons like they love to do there. So I know I'd be 10 minutes harder to find than say, Nadin Abbott, Pam Dawson, Will Pitt et al.
