Spartan AntiCheat & AntiExploit v4.0.8.8

The longest living Minecraft paid anti cheat! | 25+ Languages | Folia/Geyser/Cross-Version Support
[#] Fixed a few MorePackets teleport false positives
[#] Fixed a null pointer console error with the Spartan Edition handler
[#] Improved upon the existing statistics to make them faster and more accurate
Nice to meet you everyone, my name is Nick. As of today, Vagdedes will be stepping down from owner of the Spartan AntiCheat project and I will be taking charge in his place, with him becoming a developer. As a result of this change, our username on BuiltByBit, [Censored] & SpigotMC will soon be set to CheatSolutions and on Discord as spartananticheat. I personally am a very community driven individual and I think this will have a positive effect in this community.

So, let's begin! I'd like to give attention to 2 important issues:
1.
The 1st issue we knew is the anti-cheat's Machine Learning. Don't get me wrong, it is working but is difficult to coherently explain, so we replaced it with simple statistics accompanied by a classic anti-cheat violation system.
2. Upon downgrading from the Machine Learning, we discovered that the Machine Learning algorithms were correcting many false positives. As a result, we had to go through and correct them ourselves, making the native detections more stable. (Some detections that were too unstable have been temporarily disabled and will return in the future)

These 2 fundamental changes seem to have worked wonders. Beyond them, the plugin was found in an excellent state. Now that Spartan is under new management, pawsashatoy and I hope those of you who are unhappy with the project or have completely given up on it to give it another shot.
