Virgin Media has become the latest broadband provider to block access to pirate film and music website Newzbin 2.
The firm took action after receiving a court order from the Motion Picture Association - following the earlier example of rivals BT and Sky.
In a statement, Virgin Media said it is a "responsible" company which complies with court orders addressed to the company.
However, the firm cast doubt on whether website blocks will achieve the desired result of preventing online copyright infringement.
"[We strongly believe] that changing consumer behaviour to tackle copyright infringement also needs compelling legal alternatives to give consumers access to great content at the right price," Virgin Media stated.
Earlier this year, a number of UK broadband providers blocked consumer access to The Pirate Bay, following court action taken by music industry trade body the BPI.
