Chalk another one up to ham-handed government action against an ISP. Pennsylvania police all but dismantled an entire Usenet provider in order to get access to the information on a few newsgroups. Granted, it was a child porn case, so one can understand their urgency, but cases like this illustrate what is wrong with the way that law enforcement operates. Maybe things will get better in the future when (hopefully) newer generations of cops will actually understand some of the popular Internet protocols out there, but I doubt that.
Usenet is interesting because when you post a message to a newsgroup, it gets sent all across Usenet to a myriad number of providers. Once the cat is out of the bag, damn it's out of the bag! It is a very, very useful protocol for sharing information and discussing things, but it is also a very good protocol for criminals like pedophiles to mass-distribute illegal content. Now, most of the issue could be solved with proper software and police work, but that's easier said than done when you're talking about local governments.
Sounds like you have a THE solution.
What are YOU waiting for.
After all innocent people ARE being hurt.
Act NOW!
