I know, you as an admin should know that they dont declare false-positive bans in the first four days. Check the lifted bans, search when they were banned and go to evenbalance/cod4 and try to read how much time passed since the kick ocurred to wen they declared that it might have been a false-positive kick. Do that, if you can read.
With english dont being my native, it seems that i understand more than you.
