Something like this

pawn Код:

stock ServerReasons(reasonid) {
    switch(reasonid) {
        case 0: "Incorrect password.";
}
   return 1;

write in kick log:

pawn Код:

Kicklog(playerid, ServerReasons(0));

and then in the kick log is something like this:
playerid was kicked by the server. Reason: Incorrect password.
