If still auto de-list - Considering the change in abuse patterns and technology, should the block times be increased or de-creased? Then; Ignoring pre-emptive - predictive (in advance for no reason) blocking: Does society require more specialist non auto de-list DNSBLs? (Would it be helpful to civil society, law enforcement etc to have a "child pornography" dnsbl? or a phish dnsbl? - or is the reactive time to high in order for dynamic ipv4? - but on ipv6 allocations to devices could be more 'permanent'? etc) Andre
