A piece of advice to stop or limit spam iMessages
I've been using Apple's product for years, while more and more people are starting using Apple product, the spam iMessages have become my everyday's headache, I receive average 2 or 3 spam messages sent form spammers everyday, I almost reported and blocked spammer 's every Apple ID, but the spam iMessages still come with different Apple ID, and the content is almost the same, now I have a very long list of blocked IDs, I wonder if Apple could add some limits to the using of iMessage, like if you were going to send someone an iMessage , you need to add them as a buddy or friend something first, with the receiver's permission, you could sent the iMessage.
