Unblockedsites64 is a web-based portal designed to provide access to entertainment, primarily games and apps, that are often blocked on institutional networks. These sites function by hosting content on "mirrored" or "proxy" domains that haven't yet been flagged by standard filtering software like GoGuardian or Securly.

This cycle mirrors broader internet censorship evasion (e.g., Great Firewall of China vs. Psiphon/Tor).
