If the person did something illegal, you should pursue legal action. Your best option is to remain calm and not respond. However, retaliation will only continue the cycle of vengeance. When the god of death’s Death Note is handed to a human.If someone exacts revenge on you, it may be tempting to retaliate.Conditions to stay in the human world are as follows: The god of death must not stay in the human world without a particular reason. He pretended to the Death God that the Death Note was his, so he could obtain ownership after 490 days and at that time the story starts. Therefore when Ryuk found Sidoh's Death Note, he saw a once in a lifetime opportunity to have some fun. But according to How to Use: XXIV, Death Gods are not allowed to stay in the human world for long periods of time. Ryuk was bored and didn't feel alive in the Death God world. When I told the King of Kings what it looked like, he said, "Oh Ryuuk said it was the one he'd lost, and took it with him" At which the King replies that Ryuk had already taken that Death Note, pretending it to be his. This time he realized he had lost his Death Note and had asked the King of Gods, whether he had seen his Death Note. If you lose the Death Note or have it stolen, you will lose its ownership unless you retrieve it within 490 days. According to How to Use: XII, you lose ownership when the Death Note is stolen, unless it is retrieved within 490 days, which it wasn't. Which explains how Ryuk became the owner of this Death note. From this we can see that Sidoh is a lazy and clumsy Death God, who did not realize he was missing his Death Note for at least 6 years. This happens in 2009, 6 years after Ryuk had dropped his/Sidoh's Death Note on earth.

Sidoh says that he thinks it is about time to kill a human or two. It looks like Ryuk tricked the king of Gods by pretending he had lost his Death Note.
