Goonswarm spymaster The Mittani took a different approach with his latest EVE Online column at Ten Ton Hammer, and conducted an interview with a corporate saboteur titled "The Most Dangerous Agent". While it should be stated that most players in EVE do not engage in espionage, it's a career path of sorts that any player could potentially engage in, provided they have the combination of intelligence, social skills, and dedication needed to succeed. It's that aspect of dedication which often goes unmentioned -- the challenge of maintaining long-term duplicity.
The Mittani's interview with a player anonymously referred to as "Darwin's Accelerator" explains how a player with destructive aims greater than simply engaging a few enemy ships at a time can use intel to devastating effect, wiping out entire fleets. Maintaining a persona that fits in with the target organization and thus won't arouse suspicion, however, can be difficult if the infiltrator genuinely dislikes the members that comprise the corporation or alliance.
