Splog

Spam blogs, sometimes referred to by the neologism splogs, are Web Log (or “blog”) sites which the author uses only for promoting affiliated websites. The purpose is to increase the PageRank of the affiliated sites, get ad impressions from visitors, and/or use the blog as a link outlet to get new sites indexed. Content is often nonsense or text stolen from other websites with an unusually high number of links to sites associated with the splog creator which are often disreputable or otherwise useless Web sites. Splogs have become a major problem on free blog hosts such as Google’s Blogspot service. These fake blogs waste valuable disk space, bandwidth, and pollute search engine results. The term splog was popularized around mid August 2005 when it was first used by Mark Cuban, but appears to have been used a few times before for describing spam blogs going back to at least 2003. Several splog reporting services have been created for good willed users to report splog with plans of offering these splog URLs to search engines so that they can be excluded from search results. Splog Reporter was the first service of this kind (taken from: wikipedia).

Notice: you can report splogs to: www.splogreporter.com 

Phishing

In computing, phishing (also known as carding and spoofing) is a form of social engineering, characterised by attempts to fraudulently acquire sensitive information, such as passwords and credit card details, by masquerading as a trustworthy person or business in an apparently official electronic communication, such as an email or an instant message. The term phishing arises from the use of increasingly sophisticated lures to “fish” for users’ financial information and passwords (extract from a wikipedia article).

Cybersquatting & Typosquatting

Cybersquatting is a derogatory term used to describe the practice of registering and claiming rights over brand names which are, arguably, not for the taking. Some cybersquatters put up derogatory remarks about the person or company the domain is meant to represent in an effort to encourage the subject to buy the domain from them (extract from wikipedia).

Typosquatting, also called URL hijacking, is a form of cybersquatting which relies on mistakes such as typographical errors made by internet users when inputting website address into a web browser. Should a user accidentally enter an incorrect website address, they may be led to an alternative address owned by a cybersquatter (extract from wikipedia).
