Question on cheating guide selling

If I'd accidentally found a way to get free use of a well-known cheating program that is normally charged for, would it be allowed to sell the method of doing so? I don't know what the policy on guide selling is, or what the stance is on cheating against companies that aren't Jagex.

 

I am 100% positive that you are not allow to sell guides or programs that are not made by yourself.
