Unreasonable Ban from Chat by Valk

To all,
Valk banned me for an unkown period yesterday. Nothing new? well it is to me.

The scenario was 3 clan members having a chat, First warning was for 1 word spam when catting? what the?
I warning then a ban based on the comment:
perhaps we have to sacrifice vigins ...referin to Valk.
Lame in my view. my point in writing is two fold:
1 To point out Valk's extreme bias against O-W
2 To confirm he fails to respond to any reasonable request to discuss the issue

How is it a single Admin can make ban decisions, not be prepared to discuss in a reasonable manner and not be held accountable for his actions?
