This question has already been addressed earlier in this thread, but 
I'll answer it again.

The ISPs don't have to start blocking until a majority of ISPs are 
onboard with the system.  The rest of the system would be fine, and they 
wouldn't even have to kick the user off if Cefiar's suggestion was used 
about limiting the infected machine to only run utilities to repair it 
before their link is opened back up fully.  It would also serve as a 
notification that the user is infected... and, most importantly, it 
could be mostly automated.

The basic idea is very flexible, but it seems that all you are trying to 
do is dismiss it or shoot it down with statements that have already been 
addressed.  If you spent the same effort helping to cultivate the idea 
it would become a better system that could have ISPs jumping onboard.
