So earlier today I was just looking at the VoxelBox's Mod Pack that I found thru a youtuber named SoTotallyToby, It is a pretty awesome mod pack but idk if it is allowed to use it cause it has some bad sides to it as well, does I know of it Fly mode and noclip.
I am not sure if these can be removed yet but I will update the post if I find out how to remove the stuff that might be a bit of a advantage.
If I am not allowed to use the mod then tell me and ill remove it right away, it is just a mod pack that gives a bit of client side perks but as I said it got some bad sides as well
