This is what veracrypt containers are for. Family finds a huge file named Porn.Encrypted, knows what it is in general terms, and can't get in.

There are also various systems you can set up to automatically wipe stuff if you don't enter a password every set number of days, but I think the encrypted container is easier and less prone to loss due to laziness.

Ooh, this one’s dark, even without the bonus panel. There’s only a couple kinds of unforgiveable porn and the only acceptable one is if that dude from “unforgiveable” started doing porn. And it’s the regular kind.

You're not truly living until you no longer care who finds your porn stash after you die. You won't be around to care and they can choose to delete/throw out if they don't want to look.

I should get boxes like those and just keep old electronics in them. Would go nicely with the admittedly sym linked version of xkcd 981 I have on most of my Linux installations.

Nah. If people find my taste in porn after I die, I don't care whether they are disgusted or not on account of, you know, being dead!
