One promising answer comes from the computer scientist Jon Postel, now known as “god of the Internet” for the influence he exercised over the emerging network. In 1981, he formulated what’s known as Postel’s Law: “Be conservative in what you do; be liberal in what you accept from others.” Originally intended to foster “interoperability,” the ability of multiple computer systems to understand one another, Postel’s Law is now recognized as having wider applications. To build a robust global network with no central authority, engineers were encouraged to write code that could “speak” as clearly as possible yet “listen” to the widest possible range of other speakers, including those who do not conform perfectly to the rules of the road. The human equivalent of this robustness is a combination of eloquence and tolerance — the spirit of good conversation. Trolls embody the opposite principle. They are liberal in what they do and conservative in what they construe as acceptable behavior from others. You, the troll says, are not worthy of my understanding; I, therefore, will do everything I can to confound you."
(Wow! This is exactly the attitude of some Christian leaders I know!! In fact, a Christian pastor recently expressed in estonishingly similar language the very same intentions!)
"Of course, none of these methods will be fail-safe as long as individuals like Fortuny construe human welfare the way they do. As we discussed the epilepsy hack, I asked Fortuny whether a person is obliged to give food to a starving stranger. No, Fortuny argued; no one is entitled to our sympathy or empathy. We can choose to give or withhold them as we see fit. “I can’t push you into the fire,” he explained, “but I can look at you while you’re burning in the fire and not be required to help.” Weeks later, after talking to his friend Zach, Fortuny began considering the deeper emotional forces that drove him to troll. The theory of the green hair, he said, “allows me to find people who do stupid things and turn them around. Zach asked if I thought I could turn my parents around. I almost broke down. The idea of them learning from their mistakes and becoming people that I could actually be proud of . . . it was overwhelming.” He continued: “It’s not that I do this because I hate them. I do this because I’m trying to save them.”
