There is a companion finding on this site showing that the world’s most-blocked websites are gambling and pornography, not news. That is true — but it is the broad picture: lots of countries each block a handful of casino and adult domains as routine licensing or morality law. Ask a different question — not “what does the world block” but “what do the heaviest censors block” — and a second, opposite picture appears. The countries that censor deeply (hundreds of domains, not a dozen) overwhelmingly target political speech, not vice. The same dataset answers the two questions with two different villains.
Voidly’s /v1/measurement/intent-profile takes the domains a
country blocks nationally — confirmed across at least three
independent networks — and joins them to the 14,000-domain Citizen Lab
category list, then reports three deliberately low-contestation focus shares:
political speech (news, human rights, political criticism),
regulated “morality” content (gambling, adult,
drugs), and circumvention tooling (VPN/anonymity). Of the
countries with a meaningful national-block list, here is where the depth sits.
| Country | Domains blocked (tagged) | Primary focus | Tell-tale categories |
|---|---|---|---|
| Iran | 789 (788) | speech | News 110 · Human Rights 81 · VPN/anon 75 |
| Russia | 608 (605) | speech | News 264 · VPN/anon 57 · Human Rights 35 |
| Saudi Arabia | 121 (121) | speech (mixed) | News 35 · Gambling 18 · Political 13 |
| — | — | — | — |
| Indonesia | 256 (256) | morality | Porn 51 · Gambling 47 · LGBTQ 20 |
| Thailand | 83 (83) | morality | Gambling 21 · Porn 19 · Drugs 7 |
| Turkey | 124 (124) | morality (mixed) | Gambling 24 · Porn 18 · News 17 |
Read it top to bottom: the two heaviest national censors in the corpus, Iran (789 domains) and Russia (608), are speech machines. Russia nationally blocks 264 news outlets — more news domains than the next-deepest country blocks of everything. Iran pairs 110 news sites with 81 human-rights domains. Then the depth flips: Indonesia and Thailand go just as deep but on gambling and adult content, with little news. Saudi Arabia and Turkey sit in between — genuinely mixed regimes that block news and vice. India’s list is the most spread of all (no single dominant category), which is itself the honest answer for India.
The most-blocked-domain leaderboard counts how many countries block each site, so it rewards breadth: betfair.com is blocked in ~10 countries because blocking gambling is legal and ordinary across a wide band of states. A single news site blocked by Iran counts once. So aggregate by domain and gambling wins; aggregate by how much one country blocks and the political censors tower over everyone. Both are true. They are not the same statistic, and conflating them is how a casino blocked in Belgium ends up in the same sentence as a news site blocked in Tehran.
The morality pole is almost arithmetical. Indonesia’s communications ministry (Kominfo) runs the TrustPositif filter, which has blocked over a million sites; of the 213,735 pages it ordered blocked in 2022, 156,975 were gambling and 51,588 were pornography — roughly 98% of the year’s blocking, with news and social a rounding error (OONI / iMAP 2022; Freedom House). That is the morality machine Voidly measures, in the censor’s own numbers. The speech pole is the mirror image: Iran and Russia rank among the world’s worst for press freedom and nationally block the news outlets themselves — RFE/RL, BBC, Deutsche Welle, Meduza and dozens more (Freedom House, Iran; Russia). Two well-documented censorship regimes, aimed at two different targets — exactly the split the confirmed-block data draws.
This describes what is blocked, not intent in any legal sense, and the
edges are soft. (1) Anomaly-based censors are under-counted.
OONI records China’s Great Firewall interference as “anomaly,”
not “confirmed,” so China shows only ~15 confirmed national-block
domains here — nowhere near its true scope. The clean speech/morality
split is most reliable for high-confirmation DNS-poisoning regimes (Iran,
Russia). (2) Coverage of the tagged subset varies. Shares are
computed over domains that carry a Citizen Lab tag (~86% of national-block
domains overall, but only 24 of Italy’s 218 — Italy’s
rotating piracy domains aren’t in the list — and small tagged
counts for South Korea and Poland). An untagged domain is excluded from the
shares, never assumed safe. (3) Free countries with tiny national-block lists
(Netherlands, Spain, Canada here) are dominated by a handful of measurement
false positives, not real policy, and are excluded from the thesis. (4) The
confirmed-block layer is a periodic snapshot — see
/v1/measurement/freshness for recency. Treat the focus shares as
a qualitative fingerprint of a censor’s priorities, not a precise budget.
