True - but two wrongs do not make a right.
If the target terminates the session by any means other than the menu then they are behaving as bad as the aggressor in many ways. Assuming we are talking about griefers and gankers here rather than genuine role-playing pirates.
It's funny you cant even think about ending the session by any other means than the menu for it to be legit.
Let's maybe consider a game where pvp can give a chance for people to defend themselves, by trying to understand, because people here like to assert about word's meanings a lot, what the word versus actually means.
Versus means people are facing each other. That's pretty much the opposite here, and that's why you are all so wrong.
