I know full well that greed will drive the stupid to do stupid things... But they'll pay the price. And worst of all, I won't be able to snag the dark they throw away and add their blood to my hot tub... It'll just fuck DRK directly. And THAT, sir, is what I find to be offensive. :-p
Actually, it seems like there is probably a good service opportunity here for White Hat hacker to penetration test all of the Masternodes and ask for payment if flaws are found.
On that note, it could be that this attacker was a white hat. This actually happened with Counterparty about a month ago. Someone found a flaw, exploited it, stole some coins and then returned them once the flaw was fixed.
This is an appropriate angle to take. Pentest the service providers to see if they're up to snuff, or just smart enough to talk circles around those they swindle...
Still leaves the question of ongoing maintenance and handling an imminent or ongoing attack... If you don't know jack, how do you do it? Pay someone some more? Exactly how much money do you think that MN is going to make for you that you don't have to do any of the work and can afford to pay for everything to be done for you? Got a butler that wipes your ass for you, too?
It's no concern to me, so I wash my hands of it. You've been warned.
