Spam everywhere! There is no excuse for anybody. Here is how you can report spams on your iCloud e-mail account. Just some simple steps and you are done.
* Right-click on the e-mail and select “Forward as Attachment.” (forwarding an e-mail as an attachment is not possible on iOS device. Hence use Mail app on OS X, or email clients like Outlook.)
* Enter “spam@me.com” in the address field and send it. (The first time you report a spam you will receive an automated response thanking you for sending and if you need more information it lets you know that someone from Apple will contact you for)
