Identifying and detecting web spam is an ongoing battle between spam-researchers and spammers which has been going on since search engines allowed searching of web pages to the modern sharing of web links via social networks. A common challenge faced by spam-researchers is the fact that new techniques depend on requiring a corpus of legitimate and spam web pages. Although large corpora of legit...

The Internet’s current architecture de-couples the cost of sending traffic from the consequences of sending traffic. Its open nature allows anyone to initiate a connection with minimal authentication. These factors account for the excessive consumption caused by spam in the email system and other service areas. At the network layer, resource consumption caused by spam is analogous to Distribute...

Presence of spam tweets in a datasetmay affect the choices of feature selection, algorithm formulation, and system evaluation for many applications. However, most existing studies have not considered the impact of spam tweets. In this paper, we study the impact of spam tweets on hashtag recommendation for hyperlinked tweets (i.e., tweets containing URLs) in HSpam14 dataset. HSpam14 is a collect...

Financial discussion boards (FDBs) have been widely used for a variety of financial knowledge exchange activities through the posting of comments. Popular public FDBs are prone to being used as a medium to spread false financial information due to larger audience groups. Although online forums are usually integrated with anti-spam tools, such as Akismet, moderation of posted content heavily rel...

This exploratory study involved interviewing 104 participants, 50 of whom reported having received a phishing email. The theoretical foundation for this research is Routine Activity Theory, whereby crime is considered to be the conseque...

The spam problem is getting worse all the time. In the paper, we propose Anti-Spam Grid, which can collaboratively filter spam messages by forming a virtual organization. We discuss the design of fuzzy CopyRank and distributed Bayesian algorithm, and describe the architecture of Anti-Spam Grid. A detailed analysis shows that the system is reliable, efficient and scalable, and an experiment show...

There are number of Anti-Spam filters that have reduced the amount of email spam in the inbox but the problem still continues as the spammers circumvent these techniques. The problems need to be addressed from different aspects. Major problem for instance arises when these anti-spam techniques misjudge or misclassify legitimate emails as spam (false positive); or fail to deliver or block spam o...
