Internet censorship is very necessary

Internet censorship is the legal control, blocking, or suppression of what people can access, view, or publish online.

How It Works
DNS tampering:
Reroutes traffic by changing domain names to false destinations.
IP blocking:
Blocks connection requests to specific web addresses or geographic regions.
Keyword filtering:
Scans and drops web pages or searches containing banned words.
Packet filtering:
Blocks data based on protocols or port numbers.

Why It Happens
Political control:
Governments suppress dissent, independent news, and opposition movements during elections or protests.
Safety and regulations:
Institutions or states block illegal material, hate speech, or content deemed harmful to minors.
Productivity:
Schools and workplaces restrict access to non-essential or distracting websites.

How People Bypass It
Virtual Private Networks (VPNs):
Encrypt traffic and route it through servers in unrestricted regions.
Alternative tools:
Use proxy servers, alternative DNS networks, and censorship-resistant software like Psiphon.
