The Minecraft Reddit has a thread discussing Mojang disallowing "pay to win" servers, though whatever originated the thread seems to have been removed. Rock, Paper, Shotgun explains that Mojang may rework the EULA for their open world blocks game to stop server operators from charging players for perks, offering the following quote from Mojang's Erik Broes: “You cannot make money with Minecraft without our permission… If you are on a server, your experience should be the same as every other player. We just do not want people to mix the pools of ‘paying people’ and ‘nonpaying people’.” There's also a clarification on what this does not cover from notch on Twitter: "You can charge for hosting servers, but not for gameplay features." He also says the EULA hasn't changed, because this situation has always been covered, expressing his hatred for F2P games, which is how he views servers offering "rewards for donations."
