Diplomacy is essentially the same in EVE as it is in real life. EVE has a huge metagame element, where various corporations (guilds) and alliances are always making deals and breaking them. I wasn't playing EVE when this happened, but Vile Rat was instrumental in getting allies for Goonswarm during their early years, which enabled them to take down one of the largest EVE superpowers. That has hugely influenced EVE's political landscape. He also served on the CSM, a real world committee of EVE players that works with CCP to improve the game as well as act as an intermediate between the players and CCP.
I hope and trust that members of CSM have no delusions that they need to be honest and fair when dealing with CCP, and Residents main focused on their goal of ripping off other players for fun and profit.
