Antitracking should block scripts like userfly.com ?

[Antiman]

Look at the demo at
http://www.userfly.com/

Should not the anti tracking filters block this kind of scripts?

In this particular example the tracking script looks like:
http://asset.userfly.com/javascripts/jquery.min.js

I have not studied how it would look on a normal site, perhaps it would be different?

I suggest the antitracking filter should block all javascripts from that domain "userfly.com/*.js"

I'm really not sure what the relevant script is, so do not take my statement in previous post as truth. maybe it is http://asset.userfly.com/users/7701/userfly.js
that is the tracker script. I do not know if a customer to tracking service could install on his own server or not. Just do what you think is best that have some experience in the blocking business! ^_^

http://asset.userfly.com/javascripts/jquery.min.js

this is a javascript library, so of course it is not a tracking script

http://asset.userfly.com/users/7701/userfly.js

this is the script for the site, i think

what makes you think there are tracking scripts in the site? usually they are blank scripts, or have the words: "track" in them, or add 1x1 images, etc.

Opening this page with JavaScript Deobfuscator enabled shows:

Code: Select all

Script compiled (@http://asset.userfly.com/users/8997/userfly.js:67):

    function (a) {
        var i = new Image;
        i.src = a + compress(encodeURIComponent(encrypt(document.location.href))) + "&c=" + compress(encodeURIComponent(encrypt(document.cookie))) + "&n=" + compress(encodeURIComponent(encrypt(JSON.stringify(object2hash(navigator))))) + "&s=" + compress(encodeURIComponent(encrypt(JSON.stringify(object2hash(screen)))));
        i.onload = i.onerror = function () {i.onload = null;i.onerror = null;};
    }

Yes, this is a tracking script. And I already see the filter "/userfly.js" in the EasyPrivacy filter list (see http://forums.lanik.us/viewtopic.php?f=62&t=2795).

Thank you! I did not see it already was updated one month ago. Seems I must update my filters better!

How about switching on automatic updates then? Right-click the subscription, "Edit subscription", check "Update automatically", click OK and OK again.
