Because the great mass of people appear to be mainly, um, jackholes, I finally gave in and implemented some hotlink blocking for the images on sites in the Mighty Genehack Web Empire. On the off-chance that you're not a jackhole but have nonetheless engaged in jackhole-ish behavior by linking directly to an image on one of my sites, you might want to reconsider. You're now sending a very different message, courtesy of everybody's good friend Goatse.
(I just realized that the title of this entry could be interpreted as a rather unfortunate pun. Not intended, I assure you. (No pun on the "ass"ure, either. Okay, stopping now.))
