Frustration is continuing to grow with the UK's new porn blocks, which would ban anyone from watching porn until they publicly proved themselves to be an adult.

The controversial new ban has been worked on for more than a year but is continuing to be delayed as the government attempts to decide how exactly it should be implemented. Now those arguing both for and against the ban have said they are irritated with the continuing mystery surrounded their introduction.

The Department for Digital, Culture, Media and Sport dismissed earlier reports the measures would come into force from April 1, saying a commencement date will be announced "shortly".

Rumours had swirled in recent weeks that the blocks could be imminent, after a series of newspapers suggested that the ban would be introduced on 1 April. But that date had never been confirmed, and appears to have emerged amid complete confusion about when they would actually be introduced.

Under the rules, adults will have to prove they are of age to view the content, using one of a number of options, such as an over-the-counter card they can buy from a shop or uploading ID documents online.
