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

> We've ended up with IP space that had a "reputation" in the past

Many of the "blacklist" operators are unreliable when correcting 
errors/outdated info in their system.   The reports I get from people 
are that blacklist operators are often arrogant and accusatory and they 
often disregard explanations because they think they know better.  Often 
these operators have anointed themselves as some type of authority but 
they rarely have any legal training and they often disregard other 
policies (such as privacy policies) because they think their issues 
trumps everything else.  These types often think their technical 
knowledge gives some some type of elevated status and they accuse 
everyone else of being spammers, too stupid to be on the Internet, and 
demand everyone follow their rules, etc.
