Xraa, the rules are clear:
If your ban is relating to cheating, you must upload the automatic screenshot made by the ban system within 24h. You can find this in your cstrike folder, under the format '[mapname]00*'. For example 'de_dust2001'. We will not accept any form of excuse should you not provide it. (CS Only).
This is Unban request rule in section 5, line 3.
Therefor, my job tells me i should deny you straight away.
But, you are lucky that the demo is clear and show no signs of wallhack. So i will let it be with just a warning now respecting the fact that you were once an admin.
But you should know that the next time you get banned, you are obliged to post the screenshot on the first post or you will be straightly denied.
Unbanned
