onet.pl detects adblock

[F4z]

uBlock Origin 1.11.0 uBlock Origin Extra 2.9 Google Chrome 56.0.2924.87

I noticed that if I have enabled uBO + uBO Extra, then this website - http://www.onet.pl/ - detects "adblock", but without uBO Extra it works "properly".

To reproduce.

1. Disable all filter list
2. Add these two rules to my filters ||csr.onet.pl^ ||gemius.pl^
3. Go here - http://www.onet.pl/
4. You will see that website is asking to disable adblock
   Screenshot

   
5. Disable uBO Extra and reload website
6. No message to disable adblock

To resolve this problem I can also add these rules: @@||onet.hit.gemius.pl/fpdata.js?href=www.onet.pl$script @@||onet.hit.gemius.pl/xgemius.js$script to my filters and it will work properly, but I wonder why these rules are needed, if without uBO Extra, I do not need them.

The site is using the name property to find out whether the WebSocket constructor has been wrapped.

It works, thank you for fix and answer.

It seems the issue is back. Using 2.11. As soon as i disable it onet.pl works fine.

It's still broken.

I see the site asking to disable the blocker without uBO-Extra, so that's not a uBO-Extra issue.

Using @@||onet.pl^$generichide fixes the detection.

I also can reproduce a problem again. Steps to reproduce in my first post.

I think, that they added something with RTCPeerConnection to their script, because I did not remember that it was before, but I might be wrong.

G = function(a) {
    try {
        if ("WebSocket" !== a.WebSocket.name || a.Object.getOwnPropertyDescriptor(a.Element.prototype, "shadowRoot").get.toString().indexOf("[native code]") < 0 || 0 === a.RTCPeerConnection.name.indexOf("bound") || 0 === a.webkitRTCPeerConnection.name.indexOf("bound")) return !0
    } catch (a) {}
    return !1
}

I don’t know what onet.pl is doing but they can find out that I use an ad blocking software and they make the text disappear. Instead of the text I get gray blocks. How to solve this?
