Basically I was wondering if it was illegal (by Australian law, but I guess any law will be handy information) for someone to post someones -- somewhat -- personal information online, such as -- or including all of -- the following: home address, mobile phone number, unlisted home phone number, place of work, place of study etc. with the intent that this person will be contacted by people they do not know and, I'm guessing, harassed by them in the form of online defamation by said strangers on social media sites etc.?
Would this be considered harassment or online defamation? Could an AVO be taken against someone who has this information -- and has "threatened" to post it online -- by the persons whose information is known, because they felt as though the person obtained the information from other people (i.e. given the information when it was not their right to know) as their home address, phone number, and unlisted phone number are not available (to their knowledge anyway) online?
