The nasty tricks by copyright companies to obtain special profits by using 'Speculative Invoicing' to trick people into paying a lot of money to help boost the companies overall profits. The underlying theme is 'do not be tricked into paying', you simply help support their process and are admitting some kind of guilt. They will continue to use this process as long as people are willing to pay. It's all a scare tactic, money making exercise.
