Rather than central moderation, which is appropriate in some cases but would lead to silly turf fights on others, GG ought to implement a simple voting system, not unlike YouTube comments (where particularly stupid things disappear after 6 downvotes).

Google really ought to consider the idea of putting NNTP back; it's obvious they don't really want to develop Groups as a tool (we can still hope for Wave to save the day, but...) and so GG looks more and more like the zombified corpse of Usenet. Perhaps if there was a push for Groups to have it's own Google Code API we might see some innovation.

Groups does have a 1-5 star rating system; I've noticed spam often gets one-star votes in groups I frequent. But that doesn't really address the problem; they ought to have a "report spam" featuer as well.

So the spammers just start reporting a bunch of good emails as spam in order to confuse the moderation system.

This actually happens in webmail quite a bit as well. Spammers open up a bunch of accounts, spam themselves, then mark their messages as "not spam". But the major vendors have figured this out.
