In February 2014 Virgin Media became the last of the UK's major Internet Service Providers to enable a network level content filter. The four biggest ISPs - BT, Sky, Virgin and TalkTalk - who combined have more than 22 million subscribers, now have the capability to block sites deemed obscene or dangerous.
At present this filtering is optional. Anyone signing up to an ISP will be given the choice of leaving the filter enabled or opting out of its protective shield. If left enabled sites which fall into more than 70 categories will be automatically blocked.
But how effective is this really, and how many of the UK's broadband subscribers have chosen to make use of it? To find out more we asked some of our visitors for their opinion.
