Pro tip for if you need to scratch out sensitive penned down text: don’t scratch it out, it’ll still be readable. Instead write other similar numbers and letters over it. Have a 9? Write a p over it, then use the circle for the bottom of an 8, then write a B over the p… it’ll be impossible to discern what the original letter or number was. Do this for all letters and you’re good.

TIL dban exists for physical media.
I find setting fire to said sensitive text is usually pretty effective.
If that’s not enough, separating the ashes and sending them to different continents works pretty well too.
