This, and keeping a record of IP addresses that were already listed
in error once (some kind of grey/whitelist). Each time a grey/whitelisted
address is scheduled for auto-listing, a script or even a human should
have a look at this before relisting it again. This wouldn't prevent
them from initial mistakes, but it would help reduce the kind of DoS
attacks they are being subject to right now.
