A research on jurisprudential judgment of filter (T.V channels, Web pages and Social websites of virtual spaces)

This paper is a jurisprudential answer to this question: " Is there any jurisprudential evidence for admissibility or obligatory of filtering and blocking T.V. channels, web pages and virtual social websites? what is this evidence?" In accordance with this research and based upon grand jurists` opinions, it can be resulted that the first principle is prohibition of preventing others to access for internet pages, T.V. channels and virtual social websites, and the reason of prohibition of possessing the heretical books can`t make their filtering mandatory. Of course, if T.V. channels, web pages and virtual social websites are the proof of the evil, evidence of preventing from the evil can include it. Meanwhile if this act causes a bodily harm and loss of proprietary or even is possession of his property (which is usually as such ), judge`s permission is required.
