Just ignore all of them. They are trying to fuck your server.
Windows32 doesn't even know what he is doing.
Mr. Rudy"_" is just copy/pasting.

public
    OnPlayerConnect(playerid)
    {
        new
            string[128],
            nameoftheplayerhaha[MAX_PLAYER_NAME]
        ;
        
        GetPlayerName(playerid, nameoftheplayerhaha, MAX_PLAYER_NAME);
        format(string, sizeof(string), "%s (%d) has joined YOUR SERVER NAME HERE", nameoftheplayerhaha, playerid);
        SendClientMessageToAll(-1, string); // You don't simply send message to all in role play servers
    }

Use this. You have to edit things according to your need though.

Just for a quick note, OnPlayerText is called when a player writes something in the chat box and presses enter. Sending a message for every player who writes something in the chat is just trolling or plain foolishness.
