YES !

While I completely disagreed with the notion that registars should play police, ICAAN is a non-profit public benefit corp.

If ICAAN is shown an autonomous address or domain that is engaged in illegal activity, yank the address back into the pool and cancel the domain name and the ability to recreate it for a year

now .. how would this be adjudicated ? excess of lawyers around California, including free speech avocates

who would pay for the, say, 2000 verifiers, lawyers / judges that would be involved ?

I'd suggest Google, as thier technology can be tweeked to search these domains out, and also identify sites with malware

Where a registrar and/or hosting system has, say, 10% of a 256 IP block being used for illegal activity, warn all domain owners on that block that in 3 days that block of addresses will be taken back into the domain name pool

a legit system will respond before it gets to that point, and self police, an illegitimate one will move the sites to new blocks, and then you yank a greater range they control

Google should have a positive vested interest in promoting legal business vs scams with thier adverts, stopping search links to malware downloads, or links to child porn

for once instead of just doing no evil, Google can fight some

Hell, even the Angel of Redmond and some major IPSes have been going after the spammers, however only ICAAN as a public *front* can be the enforcement arm turning back in address space to the RIRs for redistribution as *new* unallocated space

( yes I understand that 100s of sites can sit on 2 nameserver IPs, this doesn't fundamentally change much, all kinds of space criminals can move too, and the individuals can eventually be put in jail by regular procecution or be made too big a liability for a registrar or large webhost to deal with .. not that much IPv4 space left to waste it)

these guys make me look like an angel :)
