Why should ISPs block port 25, 135, 445, or any of the other hundreds of ports people regularly say ISPs should block? I think some broadband vendors would be happy to provide the pipe, and not block any ports. Unfortunately a lot of very vocal people regular assert it is the *ISP's* responsibility and duty to monitor and control what its subscribers do on the network. If you are going to hold the ISP accountable, then expect the ISP to want to exert some control. > Are the complaints going back to the ISP?

As anyone who has ever worked an abuse desk can tell you, the complaints go back to *EVERYONE* possibly related to (and sometimes not related to) any aspect of whatever the complaintant doesn't like. > People spent the time and effort to build a solution to the issue of port > 25 being largely open and unauthenticated.

But does it really answer the question of who is responsible for handling abuse of the service? If ISP's are not responsible for abuse using port 573, they probably don't care. If the activists are going to continue to attack ISPs anyway, then expect the ISP to want to respond by implementing controls regardless of what port is used. The AOL model of subscriber control is very tempting. What reasons does an ISP have for not controlling what their subscribers can do.
