Newsgroup Retention Time
Once a particular newsgroup is requested and approved by a certain Usenet provider, it will be posted on their service. After this new newsgroup is posted, it will be traded through peering with other Usenet providers. If this particular newsgroup passes through other Usenet providers’ filters, the newsgroup will be evident in most Usenet companies’ servers across the world.
Certain groups have been around for over ten years, some of the newer ones dealing with videos and other like subjects are decently new, but will remain with Usenet because of popularity. In essence, no one provider has the power to remove a newsgroup from all of Usenet. Nonetheless, each Usenet provider has the right to filter and remove newsgroups from their particular service at their discretion. For quality Usenet access, you can always rely on Fastusenet.org
