You could use an array of bad words:

pawn Код:

new gBadWords[][] = {
"fuck",
"shit",
"bitch"
// etc.
};
public OnPlayerText(playerid, text[])
{
    for(new i=0; i<sizeof(gBadWords); i++)
    {
        if(strfind(text, gBadWords[i], true) != -1)
        {
            ApplyAnimation(playerid,"PED","fucku",4.0,0,0,0,0, 0);
            return 0;
        }
    }
    return 1;
}

Not tested/compiled, let me know if it has any errors.
