You was trollin'! ;)
I think they need to learn the meaning of trolling! Although they are right with the other two reasons.
You may not have personally agreed to an NDA, but you're still posting quasi-illegal information from an already banned source. You're lucky Google hasn't taken the blog down yet.. (But alas, I love the content and the tidbits keep me busy at work while I'm bored! Keep it up! :p)
I doubt google is going to be worried about some guy leaking alpha content of a game when I'm sure it happens for every game that gets into beta testing. Never mind that they allow so much other stuff from the lewd to the inane to populate their different accessible mediums.
why dont u consider if google has the rights to take it down ? dont compare ur narcissistic government to a private entity. google aint sony's asswipe
