Hi. Does anyone know more about the "report spam" that I've just spotted in Google Groups messages?

(Is it new? What happens when you report a post as spam? etc.)

I hoped to have such a system some time ago:

that is not new

Thanks hebbet.

What about the actions taken by Google after a spam report?

It's not very effective. Google reviews a post only if there are many people who flag it.

Thanks, Ionut.

So a spammy post is removed (is this the action that Google take?) only after many people have flagged it, i.e. after everyone have read it? :/
