hi all i would like to no ,that if a player types /rules then they recieve some money,but so it doesnt get abused how i make it so it can only be used once per account

my command is

pawn Code:

if(!strcmp(command, "/rules", true))
    {
        new str[1111];
        str = "{FF9900}No cheating, glitching or using any script exploit! Every cheater or bug MUST be reported by /report or on forum\nNo ramming or blocking\nNo carjacking! Locking vehicles not owned by you\nNo killing, punching, carkilling or running over\nNo Spamming\nNo flaming, racism or disrespecting other players\nNo asking for admin level";
        ShowPlayerDialog(playerid,0,DIALOG_STYLE_MSGBOX,"{FF0000}Server Rules",str,"Ok","Back");
        return 1;
    }
