THIS IS A GAME BREAKING ISSUE PLEASE PLEASE PLEASE LOOK AT THIS AND FIX IT

This a game breaking issue. 30 Minutes before I'm writing this, FitMC released a video (Link: https://www.youtube.com/watch?v=90pzA8sevog ) about a GAME BREAKING exploit that could destroy all multiplayer servers. It involves loading up so many new chunks that it basically lowers the TPS to 0, and it can actually kill players by having them fall through chunks. PLEASE fix this otherwise I feel like Minecraft servers could slowly but surely die. Especially 2b2t.
