I was an accredited cyber crime investigator, which was an eye opener.
I use a different user name on every forum, although I'm only in a couple (one cycling, one ham radio, one jolly exciting Ford Fusion Forum). I use different email addresses for each, and I split my web surfing between different devices, visiting certain websites with only certain devices, and use different internet connections to surf them.
As a consequence chucking my real name, email address, forum username etc into Google brings up nothing about me aside from the one forum searcher already knew about.
It would also be impossible to find information by trying to cross reference device Mac addresses, email addresses, IP details etc.
Never say never, but why make it easy for an idiot/stalker/foreign intelligence service to track you down?
