Show HN: Netwall

Netwall (https://netwall.org) is an ultra-simple, text-only public wall.

- No accounts, no sign-ups.

- You type a message, hit enter, and it deletes itself after exactly 1 hour.

- If the community likes a post, they can click "+5m" to vote to keep it alive a bit longer.

Stack: Vanilla JS, Node/Express, Postgres. It features a few classic terminal themes (including Solarized Dark and the Openwall mailing list aesthetic), and sits behind OpenAI's Moderation API to keep it from turning into a complete swamp.
