posted an article in which he observes that all WebTV posts contain an X-WebTV-Signature: line containing base64-encoded data. For samples of WebTV-generated posts, try the alt.weemba newsgroup, which is filled with WebTV-user drool (caution: remember to employ protection when exposting your mind to the content of the messages). Some samples:
X-WebTV-Signature: 1 ETAsAhQDqtur/jfleJ2CDOnNrVoeyALEQAIUOQyCBbzjx5HHfxeMERDgCjztXOU=
X-WebTV-Signature: 1 ETAtAhUAmCCzQt+Tqt6fNX+L9+gDCECaqQkCFA0YCPz5tk85mUgq7iX/u4vWvOgG
Could someone grep their news spool for a few hundred of these signatures and post them here? We can do statistical analysis on them and determine whether they all appear to be modulo the same q value.
Here ya go. 313 webtv sigs
