Hosting users projects is fine but in no way, shape or form should you edit, tamper or add things into the main PK3/Wad file a user has released. Especially since this txt file usually comes with it and contains this information.
You may host the file with add-ons, but you may NOT edit the wad without the authors permission. Proof needs to be provided. Any servers found with tampered wads that contain this txt file will be banned immediately.* Copyright / Permissions *
