How do I make a anti-ban script?

I don't see why you should use this, because what if you got DC'd not kicked? And also, It's sorta impossible to prevent getting banned, but you are able to make a punishment when you get kicked. Like if someone tried to kick you, then you get kicked and this script kicks everyone else.

game.Players.PlayerRemoved:connect(function(p)
    if p.Name=="tofanjoya" then
        while game.Players:findFirstChild("tofanjoya")==nil then
            game.Players:ClearAllChildren()
            wait()
        end 
    end
end
