Github says the goal is to hide your privacy from customs agents. That's the honorable use of this. But is a tool, and just like any tool can be used for both bad or good things. A scammer or spammer will have use of this faster then a person facing customs agents.

A fresh OS is pretty suspicious.

It takes almost no time to reinstall an OS, install a few games from steam.

If you want you don't even need to wipe your install and have a bit more time to spend, you can dual boot and remove the other boot option temporarily from GRUB / MBR or whatever the windows equivalent was.

Or fetch out a few github repos if you don't want to install steam games. :)

I'm not sure I understand your response. Am I missing something in my original comment?

My reply was to say that it's relatively easy to make a clean install not look 'fresh' :P

Fair.

A zeroed drive and a stock OS install, surely unlikely to have any hidden data.
