This is nothing to do with actual child abuse or real incest porn, and they know it, this is the next step in their war against VPNs and those circumventing their internet "age" real ID checks.

This will give them what will be an ever expanding big stick to clamp down on anybody they cant force to use their ID checking system, anybody using smaller providers (VPN or Porn) to avoid the checks will be suspect of criminal activity and will have equipment seized.

The first step was to push the larger providers to comply or get out, the next step is to start to tackle the smaller providers and consumers who at least want to try to stay legal.

Its never about 100% success with clamping down, its about getting the majority to comply and having useful tools to deal with those who do not, especially as they now stand out far more.
