About IllegalStack - dniym/IllegalStack GitHub Wiki

IllegalStack is a Spigot based plugin for Minecraft servers that aims to close a significant amount of VANILLA exploits and bugs that have made it into final releases. IllegalStack works on Spigot and Paper on versions 1.8 to current, and requires no special setup or changes to go between versions.

There are approximately 25 potentially game breaking exploits (depending on your version) that allow malicious users to wreak havoc on your server, these exploits range from game crashing exploits to duplicating items on the server. A full list of protections can be found here and I am always looking for new ones and taking suggestions on how to improve the plugin.

Since it's first upload in july 2017 this plugin has grown from a simple plugin that only checked if items were in larger stacks than the vanilla limits, it has grown to a highly configurable exploit fighting machine that protects current versions as well as the earlier versions that are no longer updated or maintained by spigot/paper/mojang.

I try to act on reports of new exploits, bugs, suggestions etc as quickly as humanly possible so please don't hesitate to report an exploit or suggest a feature! You can use the Issues Page here on github, send me a message via spigot or hop on my discord and send a message!

IllegalStack is a free plugin, however; if you feel like sending a donation my way you can send one via paypal here
