Polarmarathon(.)com Referral Spam – Distribution
Such spam is usually distributed to drive hoax traffic to third-party websites. There are two main types of spam techniques used by spammers:
Ghost Referrer Spam
This type of spam is very efficient and it is the more preferred choice by spammers. The reason why it is so successful is because it uses the free HTTP connection to remain undetected just like its name suggests. Ben Travis, a researcher from viget.com has indicated that this type of spam allows the spam message to be sent by the software when it is not even on the website. It may affect different analytics and it may be so sophisticated that it may allow the spammer to choose what data to affect. The spam is also capable of making the data useless and corrupt. In case you notice a rapid spike in your Analytics data, it is most likely cause by a Ghost Referrer spam.
Web Crawlers Spam
Crawlers are also known as spiders because they crawl and analyze different website to spam. Once they have enough information the spammer may decide when the spam is to be sent out. Basically there may be two choices – whether the spam is going to be sent out massively on all the designated sites or site by site. The second choice is riskier because once flagged, the spammer will not be able to spam certain sites with this software. What is more, this particular type of spam may affect Google search results and cause your website a lot of headaches if spam is detected. Web Spiders usually target undeveloped and new websites and they quickly devaluate their data.
