The hacker known as Rawshark has quit, acknowledging he could go to jail for hacking the WhaleOil blog but defended the decision to do so.
He has also threatened to return if dirty politics continues in New Zealand.
"I know vigilantism is a dangerous final resort. I hope history judges me kindly," he said. "If I didn't do it, who would have? If I didn't do it this way, how could it have been done?
"Don't try this at home.. unless you think it's important enough to risk 7 years in jail. Think it through." In a series of tweets from the Whaledump2 account, Rawshark said he was not motivated by political leanings but by "ratf***ers"-- a term from the Watergate scandal to describe those alleged of manipulating the political system.
