Your best bet would be to demonstrate that you have read and understood the rules before posting a Ban Protest against your permanent ban. As Bello mentioned, it is the responsibility of the player to know the rules before playing on the Guard (blue) side. If you do not know the basics of Jailbreak (Free Days are a common type of day across multiple Servers) then it is even more important to read and review the rules to develop a basic understanding of how things work before jumping onto the Guard (blue) side.
With that said, if this was your first offense, then you may be given leniency after a couple of weeks. Until then, consider brushing up on the rules and give it some time. But you should know that this isn't something that will be fixed over night.
-1 for an unban for reasons listed above.
