Wow, that chart.

For those of you who missed it - EVE Online's Inferno expansion rolled out a ton of changes, including a huge oversight that allows you to farm more gold out of faction warfare than you should be able to. Rather than report it, five players from the Goonswarm took advantage of it, harvested trillions of in-game ISK, then manipulated the stock market on items and inflated prices (literally "just because we could."), then rolled around Scrooge McDuck style in the rewards. 

The chart above is the first of many things explained by CCP in a newspost today. The new faction points rewarded for nuking enemy ships - Loyalty Points - are listed above, and you can see the absolutely absurd jumps when the players manipulated the system. Sreegs said it's comparable "to foreign exchange manipulation," which is really really bad, economically.
