I found this article interesting and appropriate for those that use forums and are unaware - there is a term for a specific type of forum trolling
sockpuppet on wikipediaA sockpuppet is an online identity
used for purposes of deception. The term, a reference to the manipulation of a simple hand puppet made from a sock, originally referred to a false identity assumed by a member of an Internet community who spoke to, or about, themselves while pretending to be another person.
The use of the term has expanded to now include other misleading uses of online identities, such as
those created to praise, defend, or support a person or organization, to manipulate public opinion, or to circumvent restrictions, suspension or an outright ban from a website. A significant difference between the use of a pseudonym and the creation of a sockpuppet is that the sockpuppet poses as an independent third-party unaffiliated with the main account operator.
Sockpuppets are unwelcome in many online communities and forums.Also, the term "
meatpuppet" describes sockpuppet behaviors. For example, a meat puppet "publishes comments on blogs, wikis and other public venues about some phenomenon or product in order to generate public interest and buzz".
Beware of sockpuppets!
