How to completely eliminate any form of player DDOS (riot implement required)

Both teams should not be able to see the ID of any enemy champ. They should appear as the name of the champion and nothing more -- EKKO is EKKO -- not EDDLE SMURFY. When you view someone's game, you should not be able to see their enemy's IDs. Hell, let's just say you shouldn't be able to tell who that person is playing with either. You should only be able to know THAT player's name since you're viewing their game -- but everyone else in that game should be known by their champion's name. This would disallow malicious players from searching for an enemy's IP -- this would disallow players who stalk specific players and DDOS their team. This would stop the MAJORITY..if not ALL malicious denial of service against players. The only ones who'd be in danger at that point are streamers who show their voip information. As a very rough example, I've added a picture to show you how the game should look in terms of identifying who you're playing against. Although this idea seems incredibly strange, this would completely stop any form of DDOS against players. But honestly, is this that strange of an idea? impossible, maybe?
