The British Phonographic Industry (BPI) has written to two of the UKs larger ISPs, Tiscali and Cable & Wireless, asking them to suspend the accounts of 59 users they have identified as 'illegal file sharers.'

The BPI says they have 'unequivocal evidence' of IP addresses that were used to upload 'significant quantities' of music. Although the IP addresses were used to identify the ISPs involved, the providers are the only people able to identify the exact individuals responsible.

This marks a significant change in the BPI's tactics; previously they have targeted individuals but it seems that they are now taking it one step further and requesting the ISPs take decisive action.

Tiscali, meanwhile, said it does not freeze customer accounts automatically when asked to, but can do so following an investigation, Reuters reported.

BPI has taken legal action in 139 filesharing cases. The four that have gone to court have produced verdicts in BPI's favour, while 111 individuals have settled out of court.
