Just a heads up to anyone using these services and fighting the unblocking war, some of the guidance given by these services very much looks like taking a sledgehammer to a problem until the wall comes down with no precision at all.

For example Unlocator has given guidance to its users to block IP ranges. In the past this was just google, but someone asked me for assistance with setting up their latest attempt at defeating the unblocking-blockers and it involves blocking entire subnets owned Netflix and a few other affiliated networks (I assume), and using rules to block /30, /24 and even /16.

This wouldn't be a sledgehammer solution if they owned a whole /16, it would indeed be fitting. But checking on just three of these /16 (255.255.0.0) rules, they only needed to block a /18, a /17 and a /20. The latter is 4096 addresses, and their /16 null route subnetting rule is going to block 65536 addresses instead, of hundreds of unrelated networks.

Changing your DNS to a third party (and therefore trusting your device/entire network with them) is one thing, but trusting these guys who are suggesting to randomly disable entire chunks of the IPv4 space is very concerning, as it just screams ignorance of how networking actually works.

In fact a great target of a malicious actor would be going after one of these services, still yet to see that happen publicly at least anyway.
