That’s the AACS code that can apparently be used to crack HDDVD discs released up till now. The AACSLA group is trying to strong arm the whole internet into removing those numbers from existence.
I align with Kevin Rose, founder of Digg, in this plight. The DMCA is getting a bit to big for its own britches and something as trivial as this might be a tipping point.
I welcome debate on why I’m wrong…
