A banned news group?

I had seen a reference to a group in another news group. Neither of my news providers carry the group, so perhaps it is banned. Now, searching with Google, it looks like a news group that I would not want to see anyway, given the topic mentioned. There are several ways to check groups online. One is with http://binsearch.info. There are some other sites that list news groups, at least. The news group I had seen seems to be valid, not carried by my two news providers, and now seems to be a non-interesting topic (although from binsearch, that was not obvious).
