British internet service provider Sky has become the second to block file sharing site Newzbin 2 site over piracy claims.
Sky said it had blocked the site on December 13 after receiving a court order.
"Moving forward, as and when clear and legally robust evidence of copyright theft is presented, we will take appropriate action in respect to site blocking, which will include complying with court orders," the comany said on its website.
Britain's largest provider BT blocked user access to the site earlier this year after receiving a court order based on complaint from the Motion Picture Association (MPA).
The company used it CleanFeed technology - normally used to block child pornography - to filter the site for its users.
Following the BT court order, the rights holder group had asked other ISPs to block the site, but so far they have required individual court orders.
Virgin Media and TalkTalk, the other two large ISPs in the UK, said they would comply with a court order to block the site, but had yet to receive one.
"We are not in principle against blocking, provided a court decides. We have received no such order in respect of Newzbin," a spokeswoman for TalkTalk told the BBC.
