From here where fo i do my level 3 violation appeal.
Reach out to the controller who issued your L3 Violation via PM to have a civil discussion and then if you still want to challenge it you can @ appeals. Best of luck!
You can message @appeals if you feel the violation was unjustified. In your message please include the following
- Replay File
- Any evidence that can back your case
Please note appeals reserves the right to not remove the violation for any reason. Also note a violation cannot be appealed after 7 days.
Adding on to the comments above, I’ve linked a very useful tutorial for you to follow, on how to appeal a violation:
