The Three Rules of Thumb are:

  1. Does this action attempt to deceive anyone or allow anyone to be deceived?
  2. Does this action gain or allow the gain of privilege or advantage to which I, or someone else would not otherwise be entitled?
  3. Would I be dissatisfied by the outcome if I were on the receiving end of this action?
 If you answered No to each of these, you are good to go.

If you answered “No” to each of these, you are good to go.
