Telecom Operators in various regions make money by inserting advertisements, and Beijing Unicom is also reluctant to lag behind

Recently, some strange advertisements appeared in the lower-right corner of Douban, and they always felt very unharmonious. Today, I suddenly realized that I saw an activity "protesting against advertisement insertion by telecom operators, in the past, many people have heard of advertisements inserted by local telecom operators in other places. Today, Beijing Unicom is also reluctant to lag behind. The insertion method is also simple and crude:

 

< Html > < Head > < Title > </ Title > < Style Type = 'Text/CSS' > Body { Margin : 0px ; Padding : 0px ; Overflow : Hidden ; } </ Style > </ Head > < Body > < IFRAME ID = 'Fullframework' Name = 'Fullframework' SRC ='' Width = '000000' Height = '000000' Marginheight = '0' Marginwidth = '0' Frameborder = '0' > </ IFRAME > < Script Language = 'Javascript' Type = 'Text/JavaScript' > VaR F = Frames [ ' Fulliframe ' ]; F. Location = Window. location; Function C (){ Try { VaR D = F.doc ument; If (D && ( ' Complete ' = D. readystate )){ VaR T = F.doc ument. getelementsbytagname ( ' Title ' )[ 0 ]; Document. Title = T. innerhtml ;} Else { If (D. readystate) {window. setTimeout ( ' C () ' , 100 );}}} Catch (Ex) {}}; C (); </ Script > < Script SRC = 'HTTP: // 59.51.96.37/pagead/ADS. js? Umask = 90 & interval = 0 & vask = 2469399818 & uid = 2600068273 & pid = 72623071953059389 & o_url = Signature' Language = 'Javascript' Type = 'Text/JavaScript' > </ Script > </ Body > </ Html >

Google will find this sectionCodeSome people have been inserted across the country. It may be a set of specialized products. Although the inserted code is still common (gzip websites can also be inserted), the impact on the website is obvious: first, because IFRAME is used to load the website, the address in the address bar will not change when the link is clicked. Second, due to the insertion code and device judgment problems, multi-layer IFRAME nesting may be formed, the page rendering performance is greatly affected.

 

In addition, this kind of product is very knowledgeable about the selection of websites to be inserted. I found some website tests on the hao123.com homepage and collected the following websites:

 

Http://www.douban.com/
Http://www.1ting.com/
Http://www.xs8.cn/
Http://www.skycn.com/
Http://www.4399.com/
Http://www.tudou.com/

 

These websites have good traffic, but they are not the largest websites of this type, and there is no backend. They are soft persimmons. If they are inserted, they can only protest and condemn them. Even if some websites resort to legal channels, the result is only a penalty of 0.2 million yuan and a public apology, which may not be as good as the one-day advertising revenue of the operator. Such laws can no longer block them.
