Short answer: No, Russia is not geo-blocked. Vizno's country-level block covers the comprehensively sanctioned countries - Cuba, Iran, North Korea and Syria - plus the OFAC-designated occupied Ukrainian regions (Crimea, Donetsk, Luhansk, Kherson, Zaporizhzhia). Russia is subject to targeted rather than comprehensive US sanctions, so it is not on that list. Individual sanctions screening still applies before any payout.
Why some countries are blocked
OFAC maintains comprehensive sanctions programs against a small set of countries and regions. Because any commercial transaction - including paid episodes, memberships, tips, or currency purchases - with users there would constitute prohibited trade, Vizno blocks access from those locations at the geo level. Russia is under targeted sanctions (named persons and entities), which the individual sanctions screening on payouts handles instead.
What this means for readers in Russia
You can create an account, sign in, purchase content, and read on Vizno or Vizno Uncut like any other reader. Readers in a blocked country or region cannot, regardless of payment method or VPN use - attempting to circumvent a geo-block may result in permanent account removal.
Is this decision final?
The block list follows current OFAC obligations. If sanctions on Russia became comprehensive, Vizno would add it; the list is reviewed as regulations change, and there is no planned revision at this time.
