Spamming is just spamming until one technique came. This is perhaps one of the most ingenious moves made by those who spam. It is cleverly disguised as legitimate websites or e-mails. The illegitimacy will only be noticed upon close scrutiny. This is what most people know as a referrer spam.
Due to the widespread use of the Internet, business models have changed over the years. Instead of solely operating in a brick and mortar setting, businesses have extended their mode of operation to the electronic setting. As with the traditional means of doing business, competition is fierce in the electronic world. Website owners’ battle over page rankings in order to have more people know about their presence.
Though previously not acknowledged as a serious threat, spamming has now reached about 60% to 70% of all e-mail traffic all over the world. Different institutions and organizations, including government agencies, recognize the threat spam brings with it. Thus anti-spamming efforts have been on the rise in the past years.
