I must admit, had lucy managed to only post the vampire ads in threads about interventions to increase longevity / social skills / etc, I might have considered them worth keeping around for entertainment value. At least then we could use them as an excuse to discuss how blood transfusions from healthy donors affects various quality-of-life factors.

(I wonder how long before someone tries to start a business based around selling healthy blood / fecal transplants / etc, and how long before the FDA tells them to stop before they sell someone diseases.)
