I've actually been getting spam on my main email address, which would hardly ever receive spam in the past. I doubt it has anything to do with the anti-spam law, since spammers will just do it anyway, or take their stuff overseas. Most of the junk email I receive is coming from Asia based IP addresses, so I really don't see this law having any "major" effect. I do support it though and really hope we can crack down on spammers as much as we do on some other things
At home I am running SpamNet, which does a great job at removing the crap. I can also set filters right on my domain which move stuff to /dev/null if needed.
