What I learned is that GitHub is no longer a reasonable place to hold your personal source codes, no matter it's private or public. github is still a good place as a platform to show yourself, but it's never home like place where you hide.

YOUR ACCOUNT IS NOT YOUR ACCOUNT BUT SOME PROPERTY OF GITHUB (or Microsoft).

Since the cloud services (not only GitHub) are increasingly unreliable these days, maybe we should think more before choose to use them.
