The only callback that is called is public OnIncomingConnection(playerid, ip_address[], port) so you are going to say "block the ip" but the IPs never are the same. Making a white-list script doesn't work too because the connections use all the available slots to check if that ip is in or out in white-list and the atack connects to the server in miliseconds so it's faster than a human so the players can't connect to the server because when they try to use a slot, a "bot/attacker" uses it before

Sorry if you don't understand me, I don't have practise speaking english.
