information from a website. Although it may look like a search engine, usually because search engines does the same method by extracting
information from a website and indexing it on their own, search engines are not scraper sites. In the last few years, and due to the advent of the
Google Adsense web advertising program, scraper sites have proliferated at an amazing rate for spamming search engines.

* Sybil Attack
Named after a book called Sybil, a case study of a woman with multiple personality disorder, Sybil Attack is an attack wherein a reputation system issubverted by forging multiple identities in peer-to-peer networks. A reputation system’s vulnerability to a Sybil attack depends on how cheaply identities can be generated, the degree to which the reputation system accepts inputs from entities that do not have a chain of trust linking them to atrusted entity, and whether the reputation system treats all entities identically.A faulty node or an adversary may present itself with multiple identities in a peer-to-peer network to appear and function as distinct nodes. Bybecoming part of the peer-to-peer network, the adversary may then overhear communications or act maliciously. By masquerading and presentingmultiple identities, the adversary can control the network substantially.
* Splogs
Spam blogs or usually known as Splogs are blogs particularly made for spamming. This is used to promote affiliated websites or to increase
search engine rankings of associated sites. This in turn will increase the PageRank or backlink portfolio of affiliate websites. There is frequent
confusion between the terms “splog” and “spam in blogs”. Splogs are blogs where the articles are fake, and are only created for search engine
spamming. To spam in blogs, conversely, is to include random comments on the blogs of innocent bystanders, in which spammers take advantagea site’s ability to allow visitors to post comments that may include links. In fact, one of the earliest uses of the term “splog” referred to the latter.
* Page Hijacking
Page hijacking is a form of search engine index spamming. It is achieved by creating a rogue copy of a popular website which shows contents similarto the original to a web crawler, but redirects web surfers to unrelated or malicious websites. Spammers can use this technique to achieve highrankings in result pages for certain key words. Page hijacking is a form of cloaking, made possible because some web crawlers detect duplicates whileindexing web pages. If two pages have the same content, only one of the URLs will be kept. A spammer will try to ensure that the rogue website is theone shown on the result pages.
* Cookie Stuffing
Cookie stuffing can sometimes be a blackhat online marketing technique used to generate fraudulent affiliate sales. It involves placing an affiliate
tracking cookie on a website visitor’s computer without their knowledge, which will then generate revenue for the person doing the cookie stuffing.Income is generated when the affected user visits the target affiliate site and either creates an account or makes a purchase, depending on the termsof the affiliate agreement.

generates random comments to blogs. According to different SEO Philippines consultants, any web application that accepts and displays hyperlinkssubmitted by visitors may be a target. Adding links that point to the spammer’s web site artificially increases the site’s search engine ranking. Anincreased ranking often results in the spammer’s commercial site being listed ahead of other sites for certain searches, increasing the number ofpotential visitors and paying customers.
* Cloaking
Cloaking refers to any of several means to serve a page to the search-engine spider that is different from that seen by human users. It can be an
attempt to mislead search engines regarding the content on a particular web site. Cloaking, however, can also be used to ethically increase
accessibility of a site to users with disabilities or provide human users with content that search engines aren’t able to process or parse
