OMFG what the hell is with all the real email addresses listed - its a spammers paradise. You'd think they'd be all throwaways but there's a lot of real ones (eg. banks, communications) and also noticed a smattering of gov domains.
Of course, best thing would be not including the addresses at all (that's what professionals would do), but if they deemed it necessary, "obscuring" the addresses would at least stop the most rudimentary harvesters.
Also, why the downvotes? Have I offended anyone?
