Weird… Chinese download behavior

My company is hosting some kind of Video-Downloadserver for one of our clients. After a login you are able to see your dedicated videos. A click more and they are downloading. So far, so good.
Now, a cilent of our client wanted to participate in a fair in Shanghai. A Videowall was planned, but the chinese government first wanted to see the videos – just to be sure, there’s no „regime criticizing“ content. So they gave the login to some guy over there in Shanghai…

This one is funny and weird at the same time: On two days they downloaded the videos more than 50.000 times and generated a traffic of 965 GB (yes, that’s Gigabytes). Looks like some kind of Industry espionage to me. Do they have some kind of „IndustryTube“ over there? Who knows…
