NoCheatPlus VS Paper

Oh boy, another person with no understanding of anticheats! *inhales* - Hypixel doesn't use an external anticheat and uses their own because first of all, instabans instead of ban waves, meaning that cheat client devs can easily figure out what cased the ban if they're banned instantly. - Things like NCP wouldn't work with hypixel's custom stuff (like fireball/tnt jumping) due to the way they work, unless they just straight up disable the fly module and let cheaters fly everywhere. - NCP is literally open-source, meaning any client dev can work around it, no matter how much it's configured. - No matter what anticheat you use, client devs will try to get around it. Even if hypixel goes and uses another anticheat, client devs will always find a way. There are people who think that ruining the experience for everyone else is FUN, and they're gonna find ways to keep doing that.

We will be downloading the Minecraft server files into this directory. To preface, there are numerous variations of server JARs that can be used (e.g. Spigot, Paper, Purpur each touting their own benefits). For this tutorial, we will be working with Paper, a fork of Spigot that is optimized for performance.

PaperMC, a minecraft server has over a quarter million lines of code Github link

Paper fixed it here: https://github.com/PaperMC/Paper/commit/8493340be4fa69fa9369719272e5dff1b7a2f455
