BT has just 14 days to block customers from accessing file-sharing site Newzbin2.
A British High Court judge has given British Telecom two weeks to block access to Newzbin2, a site accused of distributing pirated content. The ruling, handed down by Mr Justice Arnold, upholds a ruling that called for a ban of access to the site in July.
Additionally, the Guardian reports that the judge is also supporting a proposal put forward by Hollywood studios (including Warner Bros, Paramount, Disney, Universal, Fox and Columbia) that would see BT ban "any other IP address or URL whose sole or predominant purpose is to enable or facilitate access to the Newzbin2 website" because he felt blocking access to the site alone would simply not be enough.
BT will also have to foot the cost of the block, which is thought to be around £5,000. The network had been arguing for the studios to pay the bill, but Justice Arnold also sided with the studios on that issue.

Same answer you cant so don't bother.
the fact that the internet is so new means judges will be ruling on something they have little or no real knowledge about... so when there told that something will work they will tend to believe, even the the most unconvincing argument. the judge doesn't understand that all sorts of connections will have to be blocked not just tracker data. they will have to stop access to vpn hosts that are used to connect to that site and then loose money by having to ban there own customers that get round there unworkable measures.
