iCloud spam
Recently I've been getting spammed by iCloud email addresses. Has iCloud been hacked?

No, it just means that spammers have picked up some iCloud users' addresses and are forging them as the 'From' address on messages - this sort of thing happens a lot, it's very easy to do. There's nothing you can do about it except delete or spam-trap them.
