If that is all you would do, there would be no consequence, because the tournaments do not have sportsmanship regulations. So I could just ignore it.
Ignore it all you want, such behaviour would make you a jerk.

As TO I would remove a player from the tournament according to the rules due to unsportsmanlike conduct.
It is knowingly and willingly abusing the rules by first ignoring them and then enforcing them when it's most advantageous to you.
