No problem, I went through all your old names just in case but I didn't seem to find any punishments under them so that's a bit weird.
As for your appeals I'm pretty sure you must have had a different forums account at the time seeing as the one you are using was just made today. Do you happen to remember the login details for that account? Without them then you won't be able to see your old appeal.
Other than that I'm not really sure what you can do, I suppose you can try and wait for other players/staff to respond or you can create a support ticket or another ban appeal.
