Ads are displayed at the end of search results in Baidu.com AdblockWebView

[scheer]

Ads are shown at the end of search results on Baidu.com. Chinese Easylist is active and the behaviour is not reproducible in ABB for Android. I have attached both logs for ABB Android and AdblockWebView for comparison (As well as Screenshots.)

Environment

Adblock Webview (95) Lightning Browser
Galaxy S7
Android 6.0.1
Easylist China
AA Disabled

How to reproduce

1. Enable Chinese Easylist from Settings
2. Visit ​http://www.baidu.com
3. Search for 'iPhone 6'
4. Scroll to the bottom of the page
5. Wait 3-4 seconds
6. Move page up and down slightly so that bottom of page is still in view

Observed behaviour

After slightly moving the end of the page, search ads are displayed.

Expected behaviour

Search ads should not be displayed.

Can you explain how to understand if it's AA or just ads? Please check it with Lightning+ABP 97.

[scheer]

• Still occurs in AdblockWebView (97) Lightning Browser. New log attached.

广告 shows that it is an ad. The same ads and or the same formats are shown in Chrome with AA enabled. They also conform to our acceptable ads criteria which are found here: ​https://acceptableads.com/en/about/criteria.

i've found the following:
1) ABB and AdblockWebView search results page looks absolutely in different ways
(i think i depends on request headers or agent string)
2) i've found XmlHttpRequest that loads ad banner at the bottom and it's not blocked by FilterEngine (passed contentType = XmlHttpREquest).

[asmirnov]

there is rule in chinese easylist and i've checked this selector to be returned by filter engine:

baidu.com##.ec_wise_ad

however it does not help and the ads is still visible

[asmirnov]

it looks like it overrides css class display and visibility properties in element's attribute style - see attached style.png.

[asmirnov]

Ads is visible even with ABP Chrome (desktop + mobile useragent)

[asmirnov]

Blocked with user-defined rule

[asmirnov]

We can prevent loading ads with the following rule:

||m.baidu.com/rec?platform=wise&ms=1&rset=ad$xmlhttprequest

See attached screenshot with prevented loading ad.

[asmirnov]

BTW, useragent to reproduce is "Mozilla/5.0 (Linux; Android 5.0; SM-N9005 Build/LRX21V; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/54.0.2840.68 Mobile Safari/537.36"
