I actually don't think it's that dumb. I think he's right, first of all,
So if I "hacked" into your online bank account and then sent you an email on how you should be spending your money you'd be ok with that? It doesn't matter if what he posted was right or not, he got into his account. Also, who knows what other things could have been in his private conversations?
and second of all, if zuckerberg doesnt hire him, who's the stupid one.
Good idea, might as well just post "Hey everyone, if you can hack into our servers we'll give you a job here." I'll try this with Steve Jobs' email account to get a job at Apple!
