This is an Datapack I coded a long time ago. It's an Anticheat Datapack which is gonna detect Range and Flying if in Survival Mode. If it's not configured it will just tell the person who's cheating that he/she is cheating with a simple chat message. You can simply edit it by editing the file named "check.mcfunction" in the folder "functions/anticheat" in the third and seventh line after the "run" you can paste your command which is gonna be executed by the person whos cheating, such as /ban or /kick or anything you want. There could be an Update in the future.
