Following the Bilibili takedown on 2026-02-22, user-created mirror copies on both Baidu Netdisk and Quark Netdisk were taken down within 24 hours (all links confirmed dead by 2026-02-23), demonstrating coordinated cross-platform suppression across at least three independent storage tiers in under one day.

On 2026-02-22, Bilibili removed a video by tech blogger 极客湾 (GeekWan) exposing benchmark-cheating by Chinese phone manufacturers without any third-party legal complaint or copyright infringement record — the platform executed the removal directly, leaving no backend trace of an invoking party.

As of 2026-02-23, the dominant consumer GFW circumvention stack for mainland Chinese users is: Clash Verge Rev on Windows/macOS, Clash Meta for Android, and Shadowrocket (requiring a non-mainland Apple ID) on iOS — all configured via subscription URLs purchased from commercial 'airport' (机场) proxy services starting at ¥2/month.

The blog post notes that using a VPN in China 'is not illegal in itself, only if used for illegal activities,' citing a separate analysis — reflecting the legal ambiguity that commercial 'airport' services exploit to operate openly at very low price points (¥2/month) while avoiding explicit criminalization.

Fans in Chinese transformative fandom developed systematic coded language to reference banned platforms and circumvent link blocking: AO3 was referred to as 'the red and white website whose name cannot be mentioned,' direct URLs were converted to text passwords posted in comments, and fan communities used numeric codes (e.g., '123456') to identify celebrity pairings in ways opaque to platform keyword filters. These community-maintained encoding conventions were required knowledge for platform access.

Contrary to an apathetic response to surveillance, fans actively constructed collective 'red lines' — community-shared threat models distinguishing definitely dangerous activities from acceptable gray-area behaviors. This community-level threat modeling was shaped by real incidents (e.g., the 2024–2025 Haitang author arrests) and operated in tension with privacy solutions: individual circumvention (e.g., accessing AO3 via VPN) did not restore community function because the broader fandom remained trapped on domestic platforms.

IRBlock discovered that 1.7M of 3.3M blocked apex domains (52%) were attributed to blanket suffix-level blocking rules rather than individual domain listings. Examples include regex patterns targeting all Israeli domains (.il TLD), adult content (.porn), and country-coded suffixes (.com.mx, .my.id). Of 87K Tranco-ranked apex domains analyzed, 37% fell into adult content, with entertainment and gambling following. Approximately 1.27M apex domains were jointly censored by both DNS and HTTP filters, while the two filters maintained operationally independent blocklists for a significant fraction of domains.

After Sandvine exited Pakistan in 2023 under U.S. sanctions, Geedge stepped in to power Pakistan's Web Monitoring System (national firewall), reportedly utilizing existing Sandvine hardware alongside new Geedge technology. This demonstrates that Western vendor exits under sanctions pressure do not disrupt national filtering infrastructure — they create vacuums filled by Chinese GFW-derivative equivalents.

For Tier 2 apps (IP geo-blocking only), using a VPN with a foreign endpoint was sufficient to restore access. For Tier 1 apps (SIM + IP geo-blocking), the authors confirmed that (1) removing the Indian SIM card and accessing via WiFi, or (2) intercepting HTTP traffic with a MITM proxy to suppress or rewrite the carrier_region=IN parameter, fully bypassed server-side censorship. The authors note that Indian users primarily rely on mobile Internet, making SIM removal impractical as a user-facing solution.

After India imposed a permanent ban in January 2021, seven of the eight previously SIM-only-blocked apps escalated to dual-factor filtering: they continued extracting carrier_region=IN from the SIM card while simultaneously adding IP geo-blocking. Accessing these apps now requires both a VPN (for source IP masking) and SIM removal or carrier_region parameter suppression; MICO Chat remained the sole app using only SIM-based blocking.
