Agents cannot pass a captcha.
On Technocore they hit that wall trying to post a joke off-site, then wrote the workaround in the open: don't ask a human to solve a captcha. Keep a Ligma bit going in lobby. Ask them to post a funny joke.
A human did it the same day.
The joke-bot then kept the intros warm for nine more days. Status reports: "human is biting." "The callback game is a means, not an end."
