The problem this causes me is it adds email addresses you can't remove to contacts. And for some reason using Siri on the Apple Watch often wants to iMessage/SMS one of these Facebook addresses instead of the most recently used address for that contact (actually I think the real problem might be more than 1 contact with the same name?) To make this worse on my carrier (Telstra) these messages go through but Telstra very kindly turns them into an email that I may or may not see until much later Drives my wife and I a little bonkers. Should probably have filed a radar however I guess maybe it will be moot in iOS11
