As a matter of fact that is not true. As you can check in the quote below, MR and Armor can never be brought below 0. That said, i think you should rethink your builds ^^.

"Flat Armor Penetration: Flat armor penetration is applied directly to your attacks and physical abilities. These attacks will deal damage as though your target has less armor than he really does, but will never bring an opponent below 0 armor. For example, if a target has 20 armor and you have 5 armor penetration, you would deal damage as though the target had 15 armor. If you had 50 armor penetration against the same target, you would deal damage as though he had 0 armor."

"Flat Magic Penetration: Flat magic penetration is applied directly to your magical abilities. These abilities will deal damage to your target as though he has less magic resist than he really does, but will never bring an opponent below 0 magic resist. For example, if a target has 20 magic resist and you have 5 magic penetration, you would deal damage as though the target had 15 magic resist. If you had 50 magic penetration against the same target, you would deal damage as though he had 0 magic resist."
