Sounds like you don't understand the UseNet newsgroups.
There is no central location where these messages are kept so you have no
single point that you can "repair" the newsgroup. In addition, this is a
nonmoderated group so there is not anybody that can delete improper posts.
As to the 48K posts, that is all that your newsgroup server has at the
moment for the last x number of days in it's memory. There are a lot more
than that that have been posted to the group over the many years that it has
been around.
