I Censored MYSELF With A Raspberry Pi MITM Script

A practical demonstration of how ISPs and network intermediaries can block websites using Server Name Indication (SNI) inspection, even when encrypted DNS (like Cloudflare) is in use. Using a Raspberry Pi configured as a man-in-the-middle router and a Python SNI blocker script, the author shows how specific websites can be selectively permitted or blocked based on TLS handshake metadata — not DNS queries. The video illustrates real-world ISP censorship mechanisms used by governments (UK, US, France) and concludes that only a VPN can reliably bypass SNI-based blocking.
