Each ban appeal is a case by case decision. If someone has griefed 1000 blocks, but we think they're sincere and going to stop griefing, we'll unban them. If a person goes out of their way to spam, like you did, that shows a complete lack of respect to the servers staff and the servers players.
And oh look, you are still spamming. Your lack of patience is absolutely shocking. Do you have an issue where you're unable to stop yourself clicking 'post'?
