IFPI is clear on their requirements for cyberlockers to operate to their liking. Their number one desire is that they “proactively filter for infringing content” but if they don’t they must “operate an effective and efficient notice and take down system.” Failure to implement either means sites will be required to “shut down”.

Effective means to implement the spirit of the law via details like terminating the accounts of repeat infringers. Efficient means that submitting notices shouldn't be a burdonsome process.
