You shouldn't put the check inside the loop, it will be called x times, it only needs to be called once.

pawn Код:

if(GetPlayerState(playerid) == 1) // onfoot
{
    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; 
        }
    }
}

Also, please use [pawn] tags instead of php. And learn to indent.
