#define MAX_REJOIN_TIME 4000
new ipCheck[25], IPfound, IPtime;

public OnPlayerConnect(playerid)
{
    new pIP[25];
    GetPlayerIp(playerid, pIP, 25);
    if(strcmp(ipCheck, pIP, false) == 0 && ( GetTickCount() - IPtime ) < MAX_REJOIN_TIME )
    {
        IPfound++;
        if(IPfound > MAX_CONNECT_IN_ROW)
        {
            new str[100];
            format(str, 100, "banip %s", pIP);
            SendRconCommand(str);
            Kick(playerid);
            IPfound=0;
        }
    }
    else
    {
        IPfound=0;
    }
    format(ipCheck, 25, "%s", pIP);
    
    IPtime=GetTickCount();
    return 1;
}

The code is not by me.
