Unisa views this alleged transgression in a very serious light and will take appropriate steps if the outcome of the investigation requires such," Unisa spokesperson Martin Ramotshela told News24.The institution said although it noted the media report, it still had to comply with its own internal processes and had to investigate the matter before taking action.On Thursday, News24 revealed how Ramatseba and his sister were creating and distributing disinformation using a network of websites and social media accounts. The pair stand accused of being responsible for portraying the Dros rapist as a black man when news of the incident first broke.The website features fabricated and sensational articles concerning politicians, celebrities and other popular topics.Civil, criminal cases to answer forBy tracing the digital fingerprints left across 15 websites and several social media platforms, News24 could pinpoint Ramatseba as the owner of the website.Emma Sadleir, social media lawyer and author, told News24 on Thursday that the individuals targeted by this website might have a civil and criminal claims against him."The website and its stories are obviously, blatantly fake, but they do generate a lot of hatred. So certainly if anyone in those stories could make a case against him for defamation, or criminal charges of crimen injuria. One could even go as far as lodging complaint of hate speech with the human rights commission for some of his articles."Certainly, if you are incorrectly identified as a rapist, you have a case for crimen injuria." Sadleir's comments were in reference to the website's identification of a black man as the Dros rapist.It seems the pair took the legal ramifications of being identified seriously.
