For s3m3n's answer, Facebook fans plugin (e.g. LAMODA) has limitation now, you get less and less new fans on continuous requests. You may try my modified PHP script to visualize results: https://gist.github.com/liruqi/7f425bd570fa8a7c73be#file-facebook_fans_by_plugin-php
Another approach is Facebook graph search. On search result page: People who like pages named "Lamoda" , open Chrome console and run JavaScript:
var run = 0;
var mails = {}
total = 3000; //????,??????????
function getEmails (cont) {
var friendbutton=cont.getElementsByClassName("_ohe");
for(var i=0; i<friendbutton.length; i++) {
var link = friendbutton[i].getAttribute("href");
if(link && link.substr(0,25)=="https://www.facebook.com/") {
var parser = document.createElement('a');
parser.href = link;
if (parser.pathname) {
path = parser.pathname.substr(1);
if (path == "profile.php") {
search = parser.search.substr(1);
var args = search.split('&');
email = args[0].split('=')[1] + "@facebook.com\n";
} else {
email = parser.pathname.substr(1) + "@facebook.com\n";
}
if (mails[email] > 0) {
continue;
}
mails[email] = 1;
console.log(email);
}
}
}
}
function moreScroll() {
var text="";
containerID = "BrowseResultsContainer"
if (run > 0) {
containerID = "fbBrowseScrollingPagerContainer" + (run-1);
}
var cont = document.getElementById(containerID);
if (cont) {
run++;
var id = run - 2;
if (id >= 0) {
setTimeout(function() {
containerID = "fbBrowseScrollingPagerContainer" + (id);
var delcont = document.getElementById(containerID);
if (delcont) {
getEmails(delcont);
delcont.parentNode.removeChild(delcont);
}
window.scrollTo(0, document.body.scrollHeight - 10);
}, 1000);
}
} else {
console.log("# " + containerID);
}
if (run < total) {
window.scrollTo(0, document.body.scrollHeight + 10);
}
setTimeout(moreScroll, 2000);
}//1000?????,?????????
moreScroll();
It would load new fans and print user id/email, remove old DOM nodes to avoid page crash. You may find this script here
