Two of the biggest Usenet Providers and Resellers are working Hand in Hand with Anti-Piracy organisations. Those two are Giganews and Highwinds.
If you are a subscriber of one of the followings, it means you're contributing at the censorship of Usenet.
Here's the most populars: Giganews, Newshosting, Powerusenet, usenet.net, supernews, easynews, usenetserver, newsdemon...
A full list is available in the forum thread.

You should all switch to Astraweb. One of the few remaining independents in the Usenet industry that has been able to keep up with the retention of the big guys. They don't buy from anyone else, and they don't resell access to their newsgroup servers either.
Click on the banner below and subscribe to Astraweb. Support a provider that doesn't censor and remove files like the others do and you will also support us at the same time.
