Warren Ellis on limiting your availability for both productivity and OpSec:
When you reply to this, it doesn’t go to my main email. It goes to a public-facing email account that I have to manually go to. Aggressively filter what goes to your main email account and don’t give the address to everybody. Same with your phone number. Also your home address. Don’t tell anyone where you live. Move out of your house. Smash all the security cameras as you travel. Find a cave. Bury your droppings. Wear plastic shopping bags over your hands. Talk only to the sea. Only the sea understands you. Only the sea will keep your secrets.
