correct me if i'm wrong. my image of this problem.
the following takes place inside one single ISP.
A naughty customer-A will return the address after they have done
all the bad stuff that needs to be done, and say the address was
given to some good-behaving customer-B that were not effected by
black lists (e.g the address was used for VPN puroposes).
when cusotmer-C receives the address and gets blocked by blacklists,
the ISP has ways to investigate to check if it was cutomer-B
or customer-A that was doing the naughty behavior, such as
checking customer profiles, logs, etc.
now lets say if A was an ISP, B was one single corporate IT division,
C was a small data-center. If C didn't know that the prefix was owned
by A in the past, they may go and lawsuit B.
