But is ICANN supposed to clean all these random valid domains?
Ahem. Domain is not a synonym for top-level or second-level domain.
These are all domains:
foo.badguy.com
bar.badguy.com
baz.badguy.com
goo.badguy.com
Don't even think of suggesting that domains are the "same" if the last N
components are the same, until you have read and understood the endless
discussions here and elsewhere of why that doesn't work.

Yes the reputation of the domain override things, but what happens when it is
the first time a domain is seen? Does DKIM help or not?
If it did, how many milliseconds do you think it would take spammers to
start signing with random valid domains? Using wildcards for the key
records, it's a trivial little programming exercise.
