The jailbreak for iOS 10 has been long overdue. It was released last month for all 64-bit devices up to iOS 10.2. As you know, the main reason why a lot of users jailbreak is AppSync.
Update (February 3, 2017) – AppSync Unified has been updated for iOS 10/10.1.1/10.2. Read more about it here.
AppSync is a tool available on Cydia that allows you to install unsigned IPA files. AppSync was developed primarily for testing purposes.
It was geared towards developers only. However, tons of users use this powerful tool for pirating paid apps.
As always, a lot of users began asking about it on Twitter. Luca got so tired of hecklers on Twitter, he ended up blocking a lot of them.
It is not compatible with iOS 10 jailbreak and causes your device to bootloop. Even after repeated warnings, some users still installed Appsync.
I will block anyone mentioning 10.2.1, AppSync, Cydia issues, iPhone 7. And those who are unable to mention me without reply all too.

Lesson learned: you can give them jailbreaks but if AppSync doesn’t work they’re still mad.

iOS 10 devices got stuck in a bootloop as AppSync crashes installd whenever Cydia runs uicache.
