Google and other Search Engines have been strongly advising that this is bad, this is right blah blah blah. Search Engines advice users to avoid using softwares Blah Blah Blah because they minimize their Adwords/Adsense annual profits . However, there is one surprising trend which I have been seeing in the past several months. All Search Engines including Google, Yahoo and Bing have their "BLACKHAT" BOTS registered on multiple forums. I am attaching a screenshot of the cached result of Google.com when I checked for website forum.joomla.com See this screenshot I have taken today: http://i.imgur.com/Y0eintn.png Scroll down and see "Who is Online" Now some of my questions are as below a) What is the purpose of these auto register bots ? Is this a part of CIA's PRISM Program ? or Is it Matt Cutt himself Masquarading as Google Bot himself ? )) b) Why Google and other search engines snooping on private forums where content is not visible to outside users ? You can read entire Senuke Private forum while going through Google cache results without even registering on the same. c) When Content of a particular forum is not visible to outside users it is put publicly in the Google cache results ? d) What is Google Bot and other bots trying to gather ? e) Is Google, and Bing using a GSA Search Engine Ranker too to register on multiple forums and gather data ? This is why they do not want other users to use GSA ? Haha f) Isn't it simply BLACKHAT SEO ? Is Google trying to Beat Page Rank of Facebook which is now 10 and Google is at 9 (LOL). Infact, when I looked at the Cache results of forum.digital.point.com I could see 238 Robots registered and doing their work silently. When Building backlinks for any website, SEO's completely avoid websites which require Login in profile Page. Little do they know that most of the search engines are sitting ducks in most of the forums and can easily find their details, urls, signatures etc etc. I will wait for your inputs.
