First, thanks for sharing this data.
Second - why on earth would anyone create a 1.8TB zip file of 100k videos? Likely the video encoder already compressed every possible bit out of these videos, zip is not going to make it smaller. It is, however, going to make it mandatory for everyone to download the full 1.8TB file even to get a single video out of this archive. Makes me wonder what else is happening here (like the chrome only download link which is hosted on another domain, and the non-https login, and that escalator to nowhere..*)
