This is as far as I will get today. Another 30min spent without making any headway...

var casper = require('casper').create({
	verbose: true,
	logLevel: 'error',
	pageSettings: {
		userAgent: 'Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/29.0.1547.2 Safari/537.36'
	}
});

var x = require('casper').selectXPath

casper.start('http://myfreecams.com/', function() {
	this.echo(this.getTitle());
	this.page.switchToChildFrame(0);
});

casper.then(function() {
	casper.echo("Waiting for age gate...");
	casper.waitForSelector('#enter_desktop');
	casper.click('#enter_desktop');
	casper.echo("Entered.");
});

casper.then(function() {
	casper.echo("Selecting model container...");
	this.page.switchToChildFrame(0);
	
	// foreach modelRow in online_broadcasters_list
	//     if !modelRow.isLoaded
	//         scroll down
	//     
	//     foreach model in modelRow
        //         fetch data

});

casper.run();

There "switchToChildFrame" are necessary because the model list is situated within an iframe, which itself sits in another iframe.
