Leeching

My friend leeched off his friendand no,he never even took a step in Phantom forest or CWK,ever,he spent all the time CWK came out leeching,nothing else,so why is that he got abnend?

If we're going by the book, I would highly assume "Hanging on a rope after giving money to another person so they can level faster." is to play the game in a manner that is not intended by the creators. If they do something with it, though, is beyond my knowledge.

Just level normally though, I don't really see a reason to leech from ultimate castings.
