The vast bulk of USENET spam is arriving /from/ google groups.

A very effective spam filter is to simply killfile anything with an @google.groups message id.

Sadly, that also killfiles the few real posters who use GG, so if one wants to continue to see them, one has to add them as overrides to the general "kill GG" filter.

Add to the fun GFoogle Groups have stopped carrying some groups because they had too much spam. As others noted much of it was coming from google groups itself, if only it had the spam filters other usenet providers had.
