The problem is that the penalty requires prosecution by a federal district attorney. I've never managed to get a DA to prosecute perjury. I even filed a complaint against a DA once when they perjured themselves in writing. It was ruled "accidental perjury" and the case was dropped. [note: perjury has an intent element, you can't accidentally perjure yourself]

Also, the above statement is vague. The perjury clause only applies to the final clause which states that the person making the request has the authority of the rights holder. It doesn't apply to the first clause stating that the information is accurate?

I haven't read the DMCA statute in years, so I don't know if the wording in that clause parrots the wording of the statute.
