I don't think there is a specific timer on your ban. Either you're banned, or not. You should try making a proper unban request, that contains the rule your broke, a confirmation that you've read the server rules and your GUID, notr your player ID.
After you're finished with that, all you can do is wait for Wilco's decision. My impression of him is that he generally accepts ban appeals if you haven't done something really innapropriate or haven't put enough effort in your appeal. The best option for you is to edit your topic, or simply create a new one. I don't quite know the right thing to do, becuase I'm quite new here as well. After you're done with that, all you can do is pray.
