Well, you did get to somewhere where you technically weren't supposed to be. This can be interpreted as an exploit because you were exploiting a spot in the map that the map maker had not intended for you to be... ever. Although he should have given a verbal warning, written warning whether that be admin chat, the center chat, or other ways to get your attention. A day ban for something like this, is over excessive.

I'm going to unban you because this was excessive.
