Anything about our personal life that can be proven to be true is fair game for any reporter or on line blogger to report. But when it comes to pure speculation, then we do have a right to privacy and to not having our names libelled by those who just want fame.
Yes,our right to privacy extends to the publishing of allegations about our personal matters.Just because something can be published in public doesn't mean that it should or that the person who the information is being written about wants all their private information published.The best way to handle it is to get the permission of the person before publishing private information.
Saying allegations makes me think that you may be referring to something that is false. I believe our rights to privacy do extend to the publishing of allegations about our personal matters, if they are false. This is called libel. In this case, its a breach of privacy. If someone publishes the truth however, there isn't much that can be done about it.
The right to privacy is paramount, and people should not be able to publish things about other people without their permission. With the wide spread use of cell phone cameras and social networks, it has become increasingly difficult to keep personal information private on in the Internet. Nevertheless, social networks should work to remove personal data when the original owner requests so.
No, our right to privacy does not extend to the publishing of allegations about our personal matters, because we cannot be walking on pins and needles trying not to say things about each other. True defamation should be actionable. But just sharing truthful information or your opinion should not be. People should have a right to speak.
