I don’t know how to feel about your comment 
. You are correct, but the digital world leaks all to easily in the physical world and it sort of make people easier to dox or identify so I find it a bit compelling to include it.
Paper shredding is part of the offline world and falls into physical security with a separate threat model akin to guns for defense kind of discussion and we don’t and probably shouldn’t(?) do that in the website as well.
Do others feel the same way with regards to putting a shredding guide in the internet?
