Abstract
In order to increase the visibility of a target pageT, web spammers createhyperlink structures called web bubbles, or link farms. As countermeasure, special mobile agents, called web marshals, are deployed in the detection and disassembling oflink farms. Interestingly, the process of minimizing the number of web marshals and the number of hops needed to dismantle a web bubble is analogous to the graph decontamination problem. A novel distributed algorithm for graph decontamination, which can be used to define the behavior of web marshals, is introduced in this work. The new algorithm is asynchronous and topology independent. Moreover, it presents equal or better performance and needs smaller numbers of web marshals when compared to recent related works targeting only circulant graphs, a typical structure of link farms.
