Bonus points when that info actually still lives there but is now rendered inaccessible, violating the actual laws their presence is intended to comply with.

E.g. in Germany the impressum (often also called "imprint" in English versions of German websites; a mandatory page listing the physical address, contact information, registration numbers and other legal information, typically linked in the footer) must be easy to find and accessible with no more than two clicks (though this seems to be more of a heuristic than a strict legal definition).
