Hi! I was the Staff Member who banned you!
First off, please reformat your SteamID32 as this is the wrong format.
Going on about the Appeal:
Generally, in the Pantheon Button room, there is a very BIG WALL OF TEXT (https://gyazo.com/5ffdc6a8a32fafeb9744ea49fe6506fb) that states that you will be punished severely if you were to use them without authorization, so the "there was no warning or anything about the buttons" is a lie. The sounds can be heard across the entire Map and, as such, are punished accordingly.
In terms of the "accomplice", I tried to find the second guy, but I couldn't triangulate it in the Logs properly. It is always recommended to see and look at the surrounding if there are any warnings e.t.c plastered near a Area. This signifies if a area or "button" is something that staff usually flock to like hounds and immediately act upon.
I checked and you are indeed a new player so i'd agree to at least lower it down to a day.
P.S, if you COULD remember who was the second person, i'd be massively thankful if you find out and provide the name to me or another member of staff!
Thanks and good luck on the Appeal!
