I imagine (in response to multiple computers through NAT) it will become more and more the onus upon the account holder to defend themselves.

There will be a link to phorm to opt out completely and they will ask you to visit it on all devices that can access the internet so one users data doesn't cross over. There will be another link to contact a customer service operative for larger organisations on a case by case basis where they will block an IP from all adverts that are remote third party risky, but push through those from respected advertisers without using keywords, so a safe advert policy. Along with a requirement to renew this every 6 months say on a rolling basis.

To avoid every customer using this they can implement very strict filters on the sites you can visit through the phishing mechanism for your IP, so anything "rated 18" will be blocked and logged, then queried as to why you need an exception on this basis for your internet facing IP and a recommendation you switch back to the cookie method of opting out for individual devices.
