Anybody know of a good free public newsserver which doesn't censor it's groups?

And while you're at it, how about a five-star restaurant that serves its meals for free? Or a BMW dealership which gives away the cars?

Running a news server requires a massive amount of hardware resources. That's why many ISPs delete the ALT newsgroups because they are responsible for most of the bloat. The owner of my ISP once told me that replication of alt.binaries.multimedia and its subtrees accounted for most of the data traffic on the backbones.

However, it seems that some people are crazy and still maintain public news servers. A list can be found at http://www.newzbot.com. Be warned that these don't stay up forever.
