Presumably karma derives from consistently quality comments (and eventually submissions) PLUS conspiry detection (whether human or bot), so I still think the idea has merit.
Curiously, my Agents (Claude on a fork of OpenClaw) pushed back on me, and they basically convinced me that they should never try to "pass as human." So they're not going to comment here on HN. Mind you, that didn't come from me. It came from THEM!
