Pirated media(images, movies, ebooks, ROMs) uses binary posts, not text. There are different limits and retention policies for binary versus text articles, and most Usenet servers, particularly cheap or free ones, don’t host a lot of the categories a pirate would want at all.
Please don’t imply that all Usenet providers facilitate piracy.
I mean, you made me look at it again myself, as the multi-part rar files on Usenet are still very much a thing. The allowable “article” sizes for binary content are larger than for text articles, but still too small for video or high-quality audio.
