I’m a webmaster and programmer by trade. Part of my job duties involve administration of the company’s web server. As such, I do my absolute best to block all traffic from China.
Why? Because of the hacking that originates there. There’s not a day that goes by where some automated script isn’t attacking my server, and most of it originates in China. I’m not saying it’s state-sponsored, but on the other hand, there doesn’t seem any official effort to stop it, either. Perhaps it’s a matter of calculated indifference, which I surmise is a close cousin to plausible deniability.
