I got banned for buying gold in January at level 41. Had the same thoughts - wished it was only a temporary suspension/gold wipe etc I immediately pleaded guilty to the offence and hoped to be unbanned with a character wipe. It just wasn't going to happen, the GMs are very clear about it.
Decided to create a new account a month ago after having a break, now I'm lvl 37 with 145g. It's not that hard and I'm a very casual player with not much time to devote. Trust me, you'll do things differently and enjoy the game much more with a new account.
Just give up on the ban appeals, they will not take you anywhere. You are definitely not getting unbanned.
Create a new account, pick mining/skinning and focus on making gold while leveling. Don't rush to level cap, enjoy the experience.
