TOPIC: Deathrun (unban appeal)

Hello.
My Steam Name is Marania.
My Steam-ID STEAM_0:1:29580385
Admins name - Fumii
Reason - Using Speed hack
Server - Deathrunserver 94.23.19.200:27035
Time - permanent

I got permanent banned by Fumii for using a "Speed hack".
This is not true.
No one else say/see that and he/she did't give me a chance to proof it. She/He offered me a "chance to proof that i don't use a speed hack" but doen't answer when i questioned her how.
I think this is unfair and i don't know how i could have proofed this. Perhaps you can talk to her/him or do something to unban me. It was fun to play on your server , but this ban is really bad.
I have no screenshots or something to show you our convention, but please try your best to help me.

Thanksfull,
Marania
