Even profanation was prohibited, Mr. Navalani wrote. Shocking for a Russian prison, “this ban is strictly followed.”
The prison, referenced by its Russian initials IK2, has long been known for strict enforcement of regulations. Lawyers and former prisoners have described a separate, harsh punishment facility within their walls where prisoners are not even allowed to mingle or talk.
The site is typical for Russia’s colony-type prisons, which developed with some improvement from the Gulag camps established in the 1930s. The prisoners collectively reside in several dozen groups called low-slum brigades, two-story buildings surrounded by walls and barbed wire.
According to former prisoners, discipline is enforced by inmates in Caihat with the warden, a system that will allow the prison administration to strictly control the life of Mr. Navalny at all times. Nationalist politician Dmitry Dyomuskin recently told a radio station in Moscow, prisoners keep standing with their hands behind their backs for hours, looking at their feet, refusing eye contact with guards.
Mr Navalny said in Monday’s post that he had been classified as a flight risk, meaning he was reporting on his position by a guard every hour of the night.
Constant monitoring, Mr. Navalny wrote, reminded him of a dystopian novel: “I think someone read Orwell’s ‘1984’ and said, ‘Oh, awesome. Let’s do it. Education through demonetisation.’ ”
But as he has done repeatedly in recent months, Mr. Navalny still tries to radiate optimism. They have used their imprisonment to show the Russians that they need not fear Mr. Putin, as long as they believe that, sooner or later, their favor will prevail.
