Maybe I am a bit late with this idea. I remeber dns roots switching off and DNSBLs switching off. Users wont notice until broken - or not even then. The sysop has been fired. There should be a means for the DNSBL to tell its client 1) I am not a DNS-server 2) I am going to switch off soon 3) There should be a serialnumber or timestamp on the DNSBL to show when it has last been maintained. When the client sees the wrong type of server it should warn both the sysop and the user. Today it has no means to decide so.
