Thanks, I kinda glossed over the social stuff, but yeah, I think that sort of aligns with "let them delete their account". i.e. if you can sign up using FB or Twitter or whatever, if I allow you to delete your account, the social connection is broken.
Not storing social tokens... I get what they're going for there, but Apple isn't the only platform out there. I may need to do things on desktop, mobile web or android. For my uses, for example, Facebook, I only store the userid and not like a publish token or anything, but if I DID need it and requested it from the user, Apple shouldn't be able to tell me where and when I can use it.
