Anonymous

Anonymous is a unit of internet personae.  In responding to the survey, one or two people stated themselves to know nothing about the group but many more, even those who polled as considering hackers as threatening and those who polled as knowing very little about hacking or it's culture polled as knowing of the group and provided statements that were by-and-large positive and supportive for the group.  The irony comes from how those same people who condemned or were afraid of hackers support anonymous since anonymous is a hacktivist group, albeit one that crosses over into reality and becomes activists as well when it feels such measures are necessary. 

On the internet, Anonymous' activities are largely grey hat in nature with some black hat hacktivism mixed in.  The degree of black-hat versus grey-hat depends on how one views the entities that anonymous attacks.  The recent crusade against child pornography websites by the group is rather unambiguously grey-hat in nature as they infiltrate the immoral sites without permission and take them down, releasing user lists to the authorities so that those responsible can be taken into custody.  Many of their activities have however been more ambiguous and there is also the trouble of the nature of anonymous itself.  As a group if people who are 'anonymous' it is nigh impossible to tell if something has in fact been done by them or not.  Some major cyber crimes have been committed in the past that have had anonymous both confirming and denying responsibility for the action from different portions of the organization. 

Put simply, Anonymous is a mystery wrapped inside of a riddle and coated in an enigma.  Who they are can be narrowed down to a few out of the many at best, what they have and have not done is a matter of much debate with no real conclusion to be found.  On the other hand, the survey has spoken clearly, anonymous is well known and is supported by the majority of respondents despite their ambiguity.  We may never know if this faith is blind or well-placed.
