I was banging my head against the wall in a dream while talking to someone about why the Blur video for Coffee and TV was unable to transmit.
guy: "Well we've found out it's getting blocked by this network. We've seen this before, but what does this data have in common?"
me: "Okay, I understand the trend. They're filtering it because it looks too much like an advertisement."
Note 
The video features an animated milk carton:
...and it is possible that a primitive screening system might interpret the video as an ad for milk instead of an artistic work.
