The government is promoting filters to prevent children and young people from seeing content that is supposed to be for over 18s. This includes pornography and sites that talk about alcohol, smoking, anorexia and hate speech.
Filters block many sites that are not harmful to children. Sometimes they are blocked by mistake. Sometimes they are blocked deliberately. For example, many blogs and forums are blocked by default.
The Blocked! website lets you check whether a site has been blocked by these filters. The tool is free but you can support the project by joining ORG, making a donation or volunteering.
You can read more about Blocked and ISP filters in: Techdirt, Big Issue, STV, The Guardian, The Independent and Forbes.
