Social media can play a role in the violation of human rights. Social media can violate a person's privacy, often putting their reputation at risk.
However, the role they play can be even larger and more negative. For example, IS.IS has been able to infiltrate Face.book significantly. Videos have been shared where IS.IS militants have committed human rights violations. Moreover, IS.IS has often recruited people through this platform.
It is likely that the role of social media in the future will only continue to grow, which might indicate that their role in human rights violations will continue to grow as well.
