Apple Support Document Unveils iMessage Spam Reporting Tool
To report unwanted iMessage messages to Apple, please send an email with the following details to: firstname.lastname@example.orgIn late March it was reported that a group of iOS developers had been hit with denial-of-service attacks via iMessage that saw them receiving a series of rapid-fire messages. Previously, it was not possible for users to take action against possible spam attacks. Now users can alert Apple to any possible problems directly.
Include a screenshot of the message you have received.
Include the full email address or phone number you received the unwanted message from.
Include the date and time that you received the message.
Similarly, users with iOS 7 wanting to fight potential spam will have the ability to block contacts in the Messages, Phone and FaceTime apps, but users with previous versions of iOS will not be able to use that feature.
