Order of spam blocking?

Hello,
I’m thinking of installing spam karma. I already have bad behavior and askismet running. Does anyone know the order spamblockers work in?

I know bad behavior kicks in first, because it’s pasted into the top of every file you want to protect. But, does askismet or spam karma kick in first? (I hope spam karma kicks in and blocks in first, is I’d just as soon kill spam before having to moderate it in askismet.)

Thanks,
Lucia
