“Was she arrested for that video?”
I don’t know that answer. Why don’t you try searching and finding out?
None of the articles I read on her said she was arrested for anything but the church disruption. I imagine it would have been mentioned. Hence she had ended up with some years in the gulag (a work prison in Siberia is the Gulag, even if the name has changed). How is this particularly different from the Soviet Union? Oh yea, you approve this time because the Orthodox Church is ok with it.
Meh.
