MDeconstructor will prevent your client or server from running if its modpack is found to contain MCreator mods; displaying an error containing all mods found to be created using MCreator for easy removal.

MCreator is a plauge on server performance due to how it procedurally generates code, this can result in anything from a disastorus tickrate, to high RAM usage, and could even render a world unable to load!
How does it work?
MDeconstructor runs two simple checks for package names found in all mods created with MCreator; if either check succeeds, the name gets displayed and further loading is prevented.
