They require compliance with Russian laws banning political solicitation, criticism of the Russian government, or promotion of homosexuality. They also require high-volume journals (with 3000 or more visitors per day) to conform to a "draconian" Russian media law requiring registration with the Russian government and banning anonymous or pseudonymous publication. It is no longer possible to prevent ads from appearing to other readers of a journal by paying for the journal; instead, advertisements are now shown on all LJ pages unless the person viewing the page has a paid account and is logged in. Professional accounts now have 100GB of disk available while Permanent accounts have 1TB available. Current pay as you go accounts have their duration extended by 50%.
