Its really very simple....
I don't want to be Identified.
If you know someones name, and where to look you can find out all sorts of things about them....
for example:- Ever been in a newspaper? --finding that story will be easy...(most have large archives)
married? -- I do belive those records are in the Public Domain, so I can find out where, when and who you married...Legally.
...and the list goes on....
While it may all seem insignificant (and for the 'average Joe' it is) all this information could be of real interest to some wierdo/pyschopath stalker
