he who shall not be named means: Overpassers must avoid mentioning dark overlords, muggle overpowerers, harry potter haters, noseless and other names so degrading and discriminating. Name is Lord Voldemor. However, over time, it has been created to be Lord Voldemort in order to avoid being charged or reminding the murderer of innocent muggle souls. It will be missed.
