But CCP is well-known for keeping its hands off action within the game. Since no rules were broken, the changes stood, and thousands of BoB members woke up to a very different world.

Eve Isk is about the struggle between giant corporations

Scams in space

This is not the first time that rogue bankers and credit fraud have made Eve Isk seem more like the financial pages than a space cowboy video game.

In January, a player absconded with over 80bn ISK, the game's virtual currency, from an in-game bank. Although the 80bn is only worth a few thousand pounds if exchanged for real money, it represents hours of in-game toil.

In an online echo of the real-world banking crisis, the bank's chairman issued a statement to calm a run on deposits, writing: "Dynasty Banking will get over these times and we will continue to strive to earn the public's faith as one of the leading banks of Eve Isk ".

Another scam on an epic scale beyond the fantasies of real conmen was perpetrated in 2006, when a player ran off with 700bn ISK from another Eve Isk bank.

"Think of me as a space Robin Hood—steals from the rich and gives to himself," wrote the perpetrator in an EVE-related internet forum.

Such swindles left some players in awe of EVE's potential for realism, whilst others called for a stronger code of ethics in the game.

But spymaster Mittani scoffed at calls for in-game morals, noting that without dirty tricks, GoonSwarm would have had no chance of toppling a more established corporation like BoB.

He said: "We don't have any advantages, so we can't obey your stupid 'space bushido'. We're going to spy, we're going to use defectors, we're going to lie, cheat, steal and be bastards."
