I got this off Usenet, that last bastion of truth, justice and factual accuracies (yeah right). I do not know if this stuff is true or not, but it sure makes interesting reading. -mb
Ice Ice Baby
Due to installation of new security measure to monitor users of usenet, the ISPs are experiencing downtime.
The software Ice.Block installed is a data sniffer. All ISPs are required to have this service for the government.
What does Ice.Block do? It is capable of filtering data stream emerging from your computer via the ISP to the internet. For instance, to monitor say, a David Tan, the ISP simply tells Ice.Block to log every data packet originating from David. Later, a human operator will look through the reconstructed data for any thing they deem appropriate.
Alternatively, Ice.Block can be set to filter data going to certain destination. Example, if they want to know who has been accessing a certain political sensitive web site, Ice.Block will deliver the list. It is of course, up to a human operator again to access what is relevant information after that.
Significance of This Policy
As of 1999, anonymous posting to replay.com (and other remailers) are no longer 100 secure. Although you may encrypt your mail to the remailers, Ice.Block will note you have send mail to the remailers. Worst, it will have a copy of your mail (encrypted format). All the government need to do is to "mail" your encrypted note to the remailer, say 6 times more, and if the newsgroup has 7 postings - it proves your are the sender.
In short, send 7 encrypted emails through remailers and 7 postings appear in SCS - proves beyond doubt that you are the sender. It does not matter how many chain of remailers you used.
