I can't believe I have to say this, but looking at all the comments I guess it's necessary. You cannot, in any way, get banned using this or any other mod on the workshop. When you activate a mod, you're put into a special mode by the game that disables earning any progression or recording any leaderboard stats. Therefor, no matter what you do while you're in that special mode that is loaded while you're using a mod, you cannot be banned, and no progression can be made. Any mega gobblegums you use while in this mode do not get consumed on your actual online profile, and any world-record rounds you hit will not be saved. You're safe to use this mod in any way you please.
