You can. That’s what appeals are for; to appeal your ban if you believe your ban was unfair, if you broke the rules unintentionally, or if you believe that you’ve changed enough to have your ban lifted.
Can you read the rules and quote the rule(s) you broke? Do this in a new reply, don’t edit your appeal. If you do not know how to quote the rules, read the guide How to quote the rules.
If you do not identify the right rule(s) that you broke or you do not know which ones you broke, I can make it clear.
