Social media has revolutionized communication within democratic societies, becoming central to political discourse, activism, and public debate. However, in response to concerns over misinformation, hate speech, and national security, democratically elected governments have increasingly resorted to banning social media platforms or restricting access. While such actions are often justified on grounds of public interest, they raise serious questions about their compatibility with democratic principles and freedom of expression. This paper explores multiple cases including India, Uganda, the European Union, and Hong Kong using authentic data to analyze the consequences of such bans. Findings suggest that while social media restrictions may temporarily control harmful content, they often produce significant unintended effects such as economic disruption, political backlash, and self-censorship. The paper concludes by proposing policy recommendations aimed at balancing online regulation with democratic freedoms.
