Why did i get banned?

Your Warcraft III username: Roojo
Realm/Gateway:
Why are you banned: leaving TID146127 (dodging)
Why you should be unbanned: I do not know what i did wrong. I did not leave any game or dodged any ban. I honestly wish to know what i did wrong rather than getting unbanned.

ok i see. Guardian did not die on the level i left. I expected for guardian to die when i left.
