You can subscribe to Easynews. It’s Usenet turned into a website. There’s a built in search engine (supports regular expressions), retention going back to 2008, spam and malware filtering, and multiple servers located in the US and Europe. You choose whether to use the web or a Usenet client. Probably the easiest way to use this neglected corner of the Internet.

Even Usenet gets censored, but there a window of a couple days between posting and takedown where the file is available. We see this a lot with major studios who pay investigators to identify infringing material. To get around this, some uploaders are encrypting their content, and you’ll need the description key.
