Idea: as a way to incentivize powerful people to want to keep sex workers alive and healthy, encourage sex workers to keep a journal of all of their clients. If/when they die, release that journal to newspapers via an app like Killcord.

"Killcord is a tool used to build resilient deadman's switches for releasing encrypted payloads. In its default configuration, killcord leverages ethereum and ipfs for censorship resistance. The killcord project owner hides a secret key from the world by checking in to the killcord smart contract on ethereum. If the owner stops checking in after a period of time, the killcord is triggered and the secret key that decrypts an encrypted payload is published."
