Only if it impacts the ISP, which it doesn't most of the time unless they buy an unfortunate brand of dial-up concentrators.

Would you pay an extra $50/Mb a month for your ISP to operate a firewall
and scan your traffic for you?
No way. They have no business even looking at my traffic, let alone filtering it.

What would be great though is a system where there is an automatic check to see if there is any return traffic for what a customer sends out. If someone keeps sending traffic to the same destination without anything coming back, 99% chance that this is a denial of service attack. If someone sends traffic to very many destinations and in more than 50 or 75 % of the cases nothing comes back or just an ICMP port unreachable or TCP RST, 99% chance that this is a scan of some sort.
