This is what I would do, I made a simple function to set a string so that you don't need to use string = string;, which will give you trouble if the target string is a different size.

pawn Код:

stock strset(source[],destination[])
{
    for(new i; i < strlen(source); i++)
    {
        destination[i] = source[i];
    }
}

Now this is what I would do for an anti-repeat in OnPlayerText:

pawn Код:

new LastSentance[MAX_PLAYERS][128]; //At top of script

public OnPlayerText(playerid,text[])
{
    if(strcmp(LastSentance[playerid],text,true) == 0)
    {
        SendClientMessage(playerid,red,"Please don't repeat yourself!");
        return 0;
    }
    strset(text,LastSentance[playerid]);
    return 1;
}
