Was this related to the profiles about page issue? Cuz after that got resolved then so soon after that I saw the whole site went into maintenance, lol... I'm guessing just a coincidence, anyways, based on what you said about how it happened during the back-up process.
There is a huge push of mass censorship going on. The Uk govenment was the first one to pioneer the internet safety act. There were rumors floating around that The west is next.
Anywho my warning is this. Just because it never happened yet doesnt mean that it would happen overtime. X.x
