Cyberbullying has been defined as the “process of using the internet, cell phones or other devices to send or post text or images intended to hurt or embarrass another person.” The word “cyberbullying” is often used interchangeably with “cyber stalking” and in fact the Cybercrimes Act 2015 of Nigeria, uses the word “cyber stalking” which it defines as any course of conduct directed at a specific person that would cause a reasonable person to feel fear. By the provisions of the (...) Act, the transmission of any communication through the means of a computer to bully, threaten or harass another person where such communication places another person in fear of death, violence or bodily harm amounts to cyber stalking. Cyberbullying is becoming a common phenomenon in Nigeria as more people engage in it especially on social media platforms. This is carried out in various ways and a common trend is posting indecent imagery of persons online such as naked pictures or videos of persons in order to humiliate them. When posted by a person, the communication is shared by others thereby causing circulation on social media. This act amounts to cyber stalking where the intention consists of those elements stated under the Cybercrimes Act. In other situations where it is shared without the aim of humiliating the victim, such act can still be incriminated under some other laws in Nigeria such as the Criminal Code Act and the Penal Code Act which for instance both criminalise obscene publications. It is worthy of note there have been reported cases where victims of cyberbullying have committed suicide as a result of fear or shame. A major observation is that cyberbullying has gained normalcy and many internet users engaged in it do not seem to be aware of the criminal connotation of their actions. This paper examines the effectiveness of legal responses to cyberbullying in Nigeria. It discusses the forms of cyberbullying commonly perpetrated in Nigeria by citing some real life instances that have happened in the past. The paper notes that most forms of cyberbullying can be prosecuted under the Cybercrimes Act, however, there has not been any notable enforcement of the law in terms of prosecution of cyberbullying cases. It appears that the lack of prosecution of offenders has fostered the act of cyberbullying especially under the present circumstances where there is widespread ignorance among internet users. The paper also notes that the absence of image rights is a precursor in many respects to some forms of cyberbullying especially when photographs and videos of victims are involved. The paper advocates the implementation and enforcement of the Cybercrimes Act as well as other laws relating to cyberbullying in Nigeria. The paper also posits that the protection of image rights will go a long way to assist in curbing the act of cyberbullying in Nigeria. (shrink)
