There are, or were, services to allow you to send posthumous messages. I believe the way the service works is that you must check in with it periodically, but if it doesn’t hear from you after a given gap, it automatically sends the messages you’ve created. That could be a problem if you forget or are stuck somewhere without internet access.
They can torture you until you disable the service.
I thought about sending it to WikiLeaks (assuming you could trust them not to release it unless you died) because they probably couldn’t kill them all, but the baddies can still torture you or a loved one until you call WikLeaks and tell them to delete everything. For that matter, they could also torture the owners of the posthumous messaging service or the right WikiLeaks people to get it deleted too.
The plan has to be based on something that can’t be stopped, even by you, once started. I can’t think of anything.
Sidebar, please: How’d you do that funky black-out, Bricker?
I suspect that he used an ALT code, ALT-178 (▓) in particular (although ALT-219 is nice too: █).
Oh. And there I was trying to scratch it off…
