The BBC reports that the British Phonographic Industry (BPI) is to employ instant messages that will appear when internet users are downloading music illegally. The messages will warn users that their activities are illegal and will advise them that they will face court action if they do not disable their file-sharing software.
The IPKat hopes that the messaging system will be sophisticated enough to discern when downloads actually are illegal. If it cannot, it may have a chilling effect on the legitimate sharing of information.
