The discussion here is more about what to do about bystanders who are used to send out spam.
No, because SURBLs are not sender lists, but I see your point below.
Most antispam techniques are quite effective at the beginning. That rate drops as spammers come up with ways to circumvent the technique. SURBL has introduced a grey area where redirectors are used to send out a url. Given SURBL's listing policy, these domains won't be listed as it causes false positives. There is no incentive for domains which fall in the grey area to fix their redirectors.
Sure there is. Do they like having the servers hit with millions of spam redirections? Those cost resources and don't get them legitimate click throughs or whatever. It's just abuse of their systems by spammers.
Many of the organizations that have been contacted about their open redirectors being used in spams have attempted to fix them with varying degrees of success. But most realize it's abuse and wasting their resources and at least try to do something about it.
