20 British internet users have come forward following an investigation by Which? Computing magazine into letters sent out by law firm ACS Law on behalf of two game publishers. It’s working with anti-piracy firm Logistep, which identifies IP addresses that are sharing the games on P2P services so that ACS can get a court order to force the ISPs to reveal the identities of the file-sharers. Or supposed identities. “The government is basically calling for a crackdown on illegal file-sharers, which is fair enough, but we’ve got serious concerns about the process which identifies alleged file-sharers and we believe that innocent people are being accused,” says Sarah Kidner, editor of Which? Computing.
