Google Groups no longer supports new Usenet posts or subscriptions.
Historical content remains viewable.

An updated web-searchable no-login web-search archive that reports a unique
URL will need to be located that allows people to search before posting to
the s.g.s-n. newsgroup & which allows unique references to recent articles.

You can probably safely remove your Google Groups filters now.
