[address-policy-wg] "Dirty" recycled network assigned

David,

is there real things I can do?

Semi-real is 5. But the problem is much more deep. Some people make
blacklisting by firewall rules based on data years old. Some blacklists
(my client said about yahoo and aol) just have no policy to delist a
network, and ignore requests.
