Banhammers Not Enough (Unreal Tournament 2004)

As I write this, someone UsedIllegalName32 is playing on the TAM server. And it plays clearly with a trigger. F51 in skype does not respond, cheater players do not kick. What to do? Could you give someone else (not me) a banhammer for one specific server? I don't understand these intricacies, but it would be nice. And one more question - as I heard - there is no opportunity to ban after the player has left. Why? If it's a tricky technical question, you can answer "because".

PS I will immediately add right away so that Cold does not rule, Battle, you are a bad person, which I told you today without censorship. There is a certain amorphous mass of players who do not read chats, do not chat, do not kick and so on. But you are not like that. I could go into specs, look and kick, which is what I asked you to do. But you, "Poh, I'm playing simple", you don't give a damn about other players, so I think you're a bad person. I won't give up the slot anymore.

PSS "That's because of such suspicious fools as 13 we Ukraine and pissed away"
Oligophrenia or moronism?
