Graffiti? My question is always, what are you trying to accomplish? If you don't want someone to know who you are, why would anyone listen to you? Considering AI, voice and text, how do I know I'm talking to you the you I want to talk to? In the past when I worked for people with questionable ethics they would often just schedule a lunch and discussing a noisy restaurant their dealings. If they had adversarial contacts, they would have lawyers send letters. Public private keys are great yet there's still no way to verify the source if the key is compromised. I suppose, if I really wanted to send a message to someone, I would encode the message, with a shared secret or use of language, acting as a signature, and they would know it as me. My family members have verbal and nonverbal cues, noises, phrases that will tell them they're in danger or to bring a weapon or if they are under duress. I recently received my text message from an unknown number. I knew exactly who it was. I had the context and history allowing me to validate that the only person who would message me as such is a fellow HN reader.
