But the ISPs don't have to be paid for handling an infringement notice. They only need to be paid if they are to pass it on to the customer. Replying and saying "give me money" still costs money, so we may get to the worse situation where more notices are sent to ISPs (because there is a legal process for this now), but fewer notices are sent to customers (because the process isn't followed) and the ISPs have to pay for it.
