Don't even try that. You know how the gamemode works, especially if you have that many recent punishments to the point that it's led to a week long ban. You knew that what you were doing was against the rules, through basic common sense, even if it isn't explicitly stated. The basic elements of the gamemode dictate that you cannot give away your teammates or "join" the opposing team to your own.
If you continue trying to do things like this and you can't learn to just follow the rules, I would not be surprised at all if someone decided to increase the length of your ban on the grounds of loopholing and the attitude that you have shown.
