Not being a NOW broadband customer I can only guess.
What I do know is something called Broadband Buddy which offers parental controls that help keep you and your family safe online, and is available free for all NOW Broadband and NOW TV Combo members.
If you turn off your "broadband buddy" this will remove any restrictions that are in place for online viewing.
If you turn on this 'Grown up browsing time', my guess is that all sites are able to be viewed.
Have a nosy at this linke for more info about the Broadband Buddy.
