Small claims court would do nothing lol. You can't sue LO for the ban, or anything really. LO pretty much (for lack of better term), "owns our accounts". It's essentially what you agreed to when you signed up for APB. They have the right to ban, or do anything to anyone's account without any stated or valid reason.
As for the main topic of the post, you acknowledged you were wrong for what you did and did not continue the behavior. I see other members arent as smart to realize that the symbol you made was not the main point of the post. My best suggestion, like what Sergis said, contact support again. If they cant do anything, you're just SOL.
