Unless they immediately wiped the hard drive someone somewhere was or will be really weirded out.
I can just imagine,
"This iTunes library is equal parts Alan Parsons Project, scandinavian death metal, and Enya, what the hell?"
"There appear to be in depth plans for a futuristic floating city-state based on Puritan moralism, anti-imperial warmongering, and kelp farming, who was this guy?"
"Is this a project to re-write the Old Testament?- I can't quite tell."
"These can't possibly be his bank records, no financial institution in the world calculates interest like that, and why would he spend so much money at the post office?"
"Who creates an excel spreadsheet to log their Age of Empires progress?"
No calls from homeland security yet though, so we're all good.
