Indeed. And at the moment, your own argumentation isn't really positive for shortening your ban.
The moment you join a new map, you get assigned as Spectator. You then choose a team. It doesn't work any other way. When you chose a team, you either get into your assigned team or you don't, that's related to the autobalance. As we see in the video, you were assigned a team, and at some point appeared in the other team. Autobalance doesn't do that alone. The first part, assigning you to the first team, yes. The second part though, you switching the team, has to be done by yourself. This part is not allowed, as it is written down in the rules: "NOT OK: Trying to bypass autobalance".
