Urgent Issue

[w]hen we discussed the Facebook / iOS integration, one of the biggest issues we discussed was around how developers would try to use our graph to grow competitive products. [...] Within days of launching iOS6, this has already become an issue. Even though we were mostly concerned about Google before, competitive Asian social networks like Naver Line, KakaoTalk and others -- which weren't even on the map when we were initially discussing this but are now at scale -- are using the phone numbers we're putting into your contacts to bootstrap their own competitive graphs. This is a huge issue for us and it is urgent that we resolve this quickly. Every hour that goes by these social networks are getting more and more contact info from us.
