Is it just me that feels that blocking a port which is known to be used 
to perform billions of scans is only proper? It takes time to contact, 
clean, or suspend an account that is infected. Allowing infected systems 
to continue to scan only causes problems for other networks. I see no 
network performance issues, but that doesn't mean other networks won't 
have issues.
