It may be that some of these modern blocking filters have evolved beyond "reputation" and into something that might arguably be suggestive of a "class". For example, a variety of content and hosting providers are increasingly making decisions about which specific clients (source IP addresses) can utilize their service, not necessarily based on any history of IP address/block abuse, but rather on a third-party classification (or type) by IP address meta data enrichment providers. Class or type in this example might be labels such as "residential", "server", "VPN", "edu", "anycast", "content", etc. Maybe this is an irrelevant distinction based on case history, but there does seem to be some nuanced differences operationally. I wouldn't be surprised to see someone argue against some types of blocks on net neutrality grounds. Given the tussle of regulation in that space I'm not sure makes the outcome any more clear however. Just more tussle. John
