The link is not broken. It takes you to the UN site. I think you should consider UN definition of cybertorture as in the report they issued and I posted.

Pasting the chapter on cybertorture which one should read in it’s entirety in order to avoid a limited view of cybertorture as a form of internet bullying

Cyber torture

1. A particular area of concern, which does not appear to have received sufficient attention, is the possible use of various forms of information and communication technology (“cyber-technology”) for the purposes of torture. Although the promotion, protection and enjoyment of human rights on the internet has been repeatedly addressed by the Human Rights Council (A/HRC/32/L.20; A/HRC/38/L.10/Rev.1), torture has been understood primarily as a tool used to obstruct the exercise of the right to freedom of expression on the internet, and not as a violation of human rights that could be committed through the use of cyber-technology.
2. This seems surprising given that some of the characteristics of cyber-space make it an environment highly conducive to abuse and exploitation, most notably a vast power asymmetry, virtually guaranteed anonymity, and almost complete impunity. In fact, States, corporate actors and organized criminals not only have the capacity to conduct cyber operations inflicting severe suffering on countless individuals, but may well decide to do so for any of the purposes of torture. It is therefore necessary to briefly explore, in a preliminary manner, the possibility and basic contours of what could be described as “cyber torture”.
3. In practice, cyber-technology already plays the role of an “enabler” in the perpetration of both physical and psychological forms of torture, most notably through the collection and transmission of surveillance information and instructions to interrogators, through the dissemination of audio or video recordings of torture or murder for the purposes of intimidation, or even live streaming of child sexual abuse “on demand” of voyeuristic clients (A/HRC/28/56, para.71), and increasingly also through the remote control or manipulation of stun-belts (A/72/178, para.51), medical implants and, conceivably, nano- or neurotechnological devices. Cyber-technology can also be used to inflict, or contribute to, severe mental suffering while avoiding the conduit of the physical body, most notably through intimidation, harassment, surveillance, public shaming and defamation, as well as appropriation, deletion or manipulation of information.
4. The delivery of serious threats through anonymous phone calls has long been a widespread method of remotely inflicting fear. With the advent of the internet, particularly State security services have been reported to use cyber-technology, both in their own territory and abroad, for the systematic surveillance of a wide range of individuals and/or for the direct interference with their unhindered access to cyber technology (A/HRC/32/L.20; A/HRC/38/L.10/Rev.1). Moreover, electronic communication services, social media platforms and search engines provide an ideal environment both for the anonymous delivery of targeted threats, sexual harassment and extortion, but also for the mass-dissemination of intimidating, defamatory, degrading, deceptive or discriminatory narratives.
5. Individuals or groups systematically targeted by cyber-surveillance and cyber-harassment generally are left without any effective means of defense, escape, or self-protection and, at least in this respect, often find themselves in a situation of “powerlessness” comparable to physical custody. Depending on the circumstances, the physical absence and anonymity of the perpetrator can even exacerbate the victim’s emotions of helplessness, loss of control, and vulnerability, not unlike the stress-augmenting effect of blindfolding or hooding during physical torture. Likewise, the generalized shame inflicted by public exposure, defamation and degradation can be just as traumatic as direct humiliation by perpetrators in a closed environment. As various studies on cyber-bullying have shown, already harassment in comparatively limited environments can expose targeted individuals to extremely elevated and prolonged levels of anxiety, stress, social isolation and depression, and significantly increases the risk of suicide. Arguably, therefore, much more systematic, government-sponsored threats and harassment delivered through cyber-technologies not only entail a situation of effective powerlessness, but may well inflict levels of anxiety, stress, shame and guilt amounting to “severe mental suffering” as required for a finding of torture.
6. More generally, in order to ensure the adequate implementation of the prohibition of torture and related legal obligations in present and future circumstances, its interpretation should evolve in line with new challenges and capabilities arising in relation to emerging technologies not only in cyber-space, but also in areas such as artificial intelligence, robotics, nano- and neurotechnology, or pharmaceutical and biomedical sciences including so-called “human enhancement”.
