Anonymity is a powerful tool that can be beneficial or problematic depending on its use. Arguably absence of identification is important as the presence of it. It may be the case that many strong benefits from electronic anonymity will be discovered that were unforeseen and unpredicted, because true anonymity has been historically very difficult to establish. One can use anonymity to make personal statements to a colleague that would sabotage a relationship if stated openly (such as employer/employee scenarios). One can use it to pass information and evade any threat of direct retribution. For example, `whistleblowers' reporting on government abuses (economic, social, or political) can bring issues to light without fear of stigma or retaliation. Sensitive, personal, potentially damaging information is often posted to some USENET groups, a risky situation where anonymity allows conversations to be carried on completely independent of the identities of the participants. Some police departments run phone services that allow anonymous reporting of crimes; such uses would be straightforward on the network. Unfortunately, extortion and harassment become more insidious with true assurances of anonymity.
