public OnPlayerText(playerid, text[])
{
    new pos = strpos(text, "/report", true);
    if(pos != -1 && !(text[pos+9] > '9' || text[pos+9] < '0')) return SendClientMessage(playerid, -1, "Don't ask other players to report someone!"), 0;
    return 1;
}

Something like that should work. I think +9 is the offset (if it's not then just change it up or down 1.
