To be honest, I don't even need your logs... it's obvious there's a disconnect here.
In your last reply you said:
I have never personally harrased anyone. Just doing exactly like you previously stated.
Yet in another post in the discussion you admitted to
Saying this fid is garbo and that he shouldnt be building crit.
This is the perfect example of what I was trying to explain. The first portion is obviously harassment.
If you had stuck to the second portion, it would in my opinion still be slightly misplaced in a fun game mode, but it probably wouldn't have gotten you banned.
Edit: Furthermore your story seems overall a bit contradictive...
You say you were banned for yelling random stuff in URF... but your OP says the thing with fiddles happened in a diamond promo?
I have the feeling you know exactly why you were banned, or you wouldn't feel the need to lie about the situation it happened in.
