“Cyber Space Defamation Can Result In Doubled Sanctions”

Does Cameroonian law offer any protection against attacks against privacy on social media?
Yes, there are both national and international sources of these rights (laws), but I will limit myself to Cameroonian laws (national). Here we can invoke the Constitution in its preamble; the Penal Code; Law No.98 Regulating Telecommunication in Cameroon; Section 3 of Law No. 2010 Regulating Electronic Communication in Cameroon, and Law No. 2010/012 of 21 December 2010 Relative to Cyber Criminality and Cyber Security, which is a specific legislation relative thereto. Furthermore, we have both Civil Law and Common Law liabilities in the French- and English-speaking parts of Cameroon as alternative modes to seeking redress.
It goes without saying that the laws as cited cannot be respected if there were no accompanying sanctions. Namely, Sections 52 and 59 thereof the Law on Cyber Security state the procedure to be followed by any victim of violation of privacy rights.

Articles 65-71 outline various offences and penalties, including unauthorized access or using electronic means to intercept personal data without authorization. This carries imprisonment and fines. Publishing false information or propagating false information via electronic communications can lead to imprisonment and fines.
Pedophilia or designing, publishing, or propagating pedophilic content via electronic communications is punishable by law. And data protection or processing personal data without authorization or in violation of implementation conditions can result in imprisonment and fines.
While Articles 72-80 focus on the protection of privacy. This includes interception of communications or personal data without authorization during transmission, which is punishable by law. Unlawful collection of personal data or using illegal means to collect personal data to invade someone's privacy is punishable. Similarly, electronic signatures can only be created by using reliable devices with technical characteristics determined by the Minister in charge of Telecommunications.

What of the punishment for violating these laws?
Articles 81-89 cover electronic documents and signatures, as well as international cooperation in cybercrime investigations. Some notable penalties under this law include imprisonment ranging from 1-10 years for various offenses. Fines ranging from 1 million-50 million FCFA for various offenses. Under propagation of false information, corporate body offenders may be subject to fines of 5 million-50 million FCFA.
