Questions concerning anonymity on the web or internet sometimes have the same context of discussion with matters concerning the internet and privacy. This is so because anonymity can offer many of the same advantages as privacy can offer. For instance, if an individual is using the web or the internet to obtain psychological counseling or medical help, or to discuss sensitive issues such as abortion, AIDS, venereal disease, gay rights, political dissent etc. then that person can afford similar protection to the one about privacy. Likewise, both privacy and anonymity on the web or the internet can be quite helpful in the preservation of humanity values such as mental health, security, peace of mind, and self-fulfillment. It is unfortunate that those people who may want to do undesirable and unwanted activities such as drug trading, money laundering, preying upon those people who are vulnerable, or terrorism can exploit anonymity and privacy in the way the carry out their deals (Spafford, Heaphy, & Ferbrache, 1989).
