You must create a timer so that the player can see the message. Refer to the code below.

pawn Код:

// This goes were the message is being sent.
SendClientMessage(playerid, ...); // Your message goes here.
SetTimerEx("KickPlayer", 1000, false, "i", playerid);

// Put this on the bottom of your gamemode.
forward KickPlayer(playerid);
public KickPlayer(playerid)
{
    Kick(playerid);
}
