The blame should be put squarely on the shoulders of tophatter.com. They know the quality of what is being sold and choose to look the other way for the sake of making commission and sales fees on these imitation goods. In my estimation and also the interpretation of the law this is outright FRAUD.
Inverse operations are opposite operations that undo each other. Addition and subtraction are inverse operations. Multiplication and division are inverse operations.
Undoing is performing an act to 'undo' a previous unacceptable act or thought. It is often a form of apology, although it may not include the actual act of saying that you are sorry.

Examples: (1) two close friends have a violent argument; when they next meet, each act as if the disagreement had never occurred.
