How Sudden Censorship Can Increase Access to Information

New Twitter users who joined because of the Instagram block were initially apolitical (80% Chinese-language preference vs. 39% for existing Chinese Twitter users; ~80% of first follows were entertainment/sports accounts) but within two days their rate of political discussion about Hong Kong converged with that of established users. This confirms the gateway effect operates without pre-existing political motivation and without a Streisand-style backlash.

Blocked Chinese-language Wikipedia pages received approximately 160,000 more views on September 29, 2014 (the day Instagram was blocked) than in the preceding week, covering politically sensitive topics — Tiananmen Square, mainland leaders, and the PRC blocked-sites list — that long-term VPN users would not be browsing for the first time. By November 1, Chinese-language Twitter accounts had accumulated 33,750 more followers than pre-block trend projections.

When governments suddenly block previously uncensored, habitual-use platforms, affected users acquire VPN/proxy tools to restore access — and those tools then incidentally unlock all long-blocked content. The authors call this the 'gateway effect': sudden censorship backfires not through political backlash but through habit-driven evasion that permanently expands information access. The effect is strongest for indispensable, hard-to-substitute services.

China's September 29, 2014 Instagram block caused VPN Express to jump from rank 1,229 to rank 6 among all iPhone app downloads in China in a single day, and four of the top ten free productivity apps that day were VPNs (VPN Express, GreenVPN, VPNArtifact, VPN in Touch). The prior day, no VPN appeared in the top 10.

On the day Instagram was blocked, geo-located Twitter users from mainland China increased ~30% and new account creation jumped more than 600%. A full 53% of previously active Instagram users (estimated 8–16 million people) continued accessing Instagram via evasion tools after the block, compared with roughly 0.026% of all Chinese Internet users who used Twitter before the block — demonstrating the Firewall's baseline efficacy and the magnitude of the gateway-driven surge.
