Has any illegal data been saved in the Block Chain, such as an illegal number, or illegal prime?

While seeing the Bernank's face in there is repulsive, I don't think it is criminal. http://pastebin.com/raw.php?i=BUB3dygQ

While working on my master thesis I used the AACS encryption key (09 F9 11 02 9D 74 E3 5B D8 41 56 C5 63 56 88 C0), considered an illegal number, as a basis for creating a fake Bitcoin address - 1ujTAfEQh2obwdt72GrmXonakx2RxvYpX. A 1 Satoshi transaction was sent to that address from address 17TQLZvXjKTrUyRnV9DuQs4RVDgNjUPeXQ. The transaction was encoded in block 177653.

Wouldn't it be easier to just have the hex string 09f911029d74e35bd84156c5635688c0 be the private exponent? That makes the unused address 1KyKqNh9fM5sN8uWDLXNv2o52sqj94GhbN. (Generated using brainwallet.org)lurf jurv 2013-02-06T03:33:46.673

@lurfjurv But then you are not storing the illegal number, but some derivation of it which is technically not illegal.ThePiachu 2013-02-06T05:54:12.163

Oh. How does 1ujTAfEQh2obwdt72GrmXonakx2RxvYpX represent that number, then?lurf jurv 2013-02-08T16:07:16.360

2@lurfjurv It's hash160 (as in, hex version of the address that is a part of the block now) is 09f911029d74e35bd84156c5635688c000000000 .ThePiachu 2013-02-09T08:54:33.840
