why not something more random? | Peter's Custom Anti-Spam for WordPress | Forum

Could someone please explain why you would have a set amount of words to choose from in the default installation? Is there some problem with using something like below?

$casString = "";
for($i=0;$i<8;$i++){
$casString = $casString.chr(rand(97,122));
}
$cas_text[] = $casString;
