Actually, Spamhaus is very good at detecting zombies. The link provided 
is not strictly hijacked networks, though. In all cases, Spamhaus tends 
to side on a "questionable" zombie, as sometimes it's difficult to tell 
if a network was truly hijacked. As known spamhausen do hijack more 
networks and demonstrate a track record, it does lead to more easily 
detecting when a network or AS has been hijacked. In all cases, the list 
is about spam, not netblock hijacks.
