There's probably been many suggestions about this, but barely anyone paid attention to them, so i'll try it again. -Put players in Adventure Mode to prevent block glitching. Airstrikes (redstone torches) should be changed so you only need to interact with it, and not place it down. This will also fix the problem of not being able to place airstrikes down on leaves, ice, slabs, and probably more. -AntiBlockJump is a plugin that prevents block glitching, but the only problem is with the airstrikes, which can also be changed to what I suggested above. EDIT: Someone made this while I was writing this, go check it out it's much cooler https://www.mineverse.com/threads/gamemode-adventure.149482/#post-1335564
Support! Block glitching is so annoying and it's hard for mods to catch everyone doing it during the game
Boosting would still be a problem though. An easier fix would be to just block off all the block glitching/boosting areas, there's not that many.
