It's better to identify and disconnect zombied systems. Even with port 25 blocked, zombies can still do a lot of damage, such as DDoS attacks. And as this tactic becomes more popular, spammers will just find other ways to get their crap out, so it doesn't stop spam either.

The underlying problem is that "lots of users are idiots", and I don't think that's an ISP's problem to solve.

| I think it is a good short term solution to slow down the spammers. You are correct that they will find ways around it but at least it will break what they have in place for the moment.
In the long term ISP's need to force the responsibility on the end users (by making it part of their TOS) and take them offline of they don not fix their zombie computers.
