Internet censorship refers to the control or suppression of what can be accessed, published, or viewed on the internet. Governments, organizations, or service providers may restrict certain content to protect national security, prevent the spread of misinformation, or uphold social norms. This can include blocking websites, filtering search results, or monitoring online activities. Censorship can vary widely across different countries. For example, in some places, access to social media platforms like Facebook or Twitter may be limited, while in others, specific topics such as politics or religion might be heavily regulated. The balance between freedom of expression and censorship remains a contentious issue globally.
