LOL @ Robert Charlton's response.
It would be a huge waste of time and energy for Google to "tag" everyone who visits one of those forums. Black hats in particular are going to flush their caches and delete their cookies all the time, and there are a lot of ways to break up your "web footprint" so Google can't be sure which sites are yours and so on.
*Maybe* Matt is talking about targeting a few really big spammers. Maybe something like that could be worthwhile because identifying one of these spammers might lead to thousands of sites? I agree the way he puts it leaves a lot to scratch one's head about, but I have a feeling the people he's talking to know exactly what he means... and we don't, because we're not who he's talking to.
