What to say if someone random sees you developing a block game exploit

Very simple. But you have to make it seem hard and not make sense. If you don't want them to be weirded out, or if they are some sort of moderator or something, just say:

"I am designing a graphical interface for the sole purpose of editing the inside of games code which then changes the outcome of what will happen inside of this game, this graphical interface also allows for the use of user made code to be created to do nearly anything you'd like to redirect the outcome or of a file and possibly change a users experience within this. This interface is designed with the intent of style as well as to help with functionality."

If you guys have anything better to put, be sure to reply with it :)))

If you don't want them to know its roblox just replace any word that is Roblox to app, or game, or something thats almost like gaslighting them by telling them part of the truth, but not really the full truth.
