ISPs already block lots of things that arguably have legitimate uses such as blocking direct access to SMTP ports (Bell South, MSN, etc.) to stop spam from being sent from home machines, block access to open relay servers to also stop spam and even implement RBL to block spammers IPs.

Although they're trying to be helpful I don't think it should be the task of a delivery company to play justice and I wouldn't like ISP's gaining more and more power.
Neither my mailman should bother with the content of my snail mails nor the telephone company should tap my calls.
The solutions should be sought by protection on the OS level, correct standardization and eventually laws, but again, not at the cost of innocent ones.
