The Yes Men
There are innumerable strategies and motivations behind impersonation on the Internet. Some are legitimate hoaxes, others malicious, others satire. Take this typo for example: Gogle.com. Hypothetically, for every person with a sticky "o" key, or too fast of a double-keystroke, there is someone out there who is able to maliciously attack the unfortunately imperfect typist, logging history, Internet etiquette, and personal data. Inversely, one could hypothetically use similar guerilla tactics to attack companies of questionable moral standing, which is exactly what an internet-hoax group, referred to as “The Yes Men,” have done.
