[anti-abuse-wg] Hold time for abused address space - DNSChanger IP's reallocated

I dug out an e-mail someone sent me after dealing with Cisco's 
Senderbase.org reputation site:

"We are having the same problem with Senderbase. Their information is 
inaccurate and they will not tell us why we don't have a good rating. We 
are not on any blacklists, send 150,000 emails per day and have had the 
same IP addresses for seven years. They do respond but in an arrogant, 
rude, and accusatory manner." (Senderbase.org claims they are a credit 
reporting agency for IP addresses. )

Many abuse people operating these blacklists think that once they detect 
something they "know" the person is an "abuser" and, therefore, they 
have no rights and any of their objections should be disregarded.  
Either that or the person is regarded as "clueless" and any related 
legal threat is a "cartooney."
