In addition to all the homophobia and racism she will be facing, I hear it’s cold in Siberia this time a year.
Not Siberia, but Mordovia about 270 miles SE of Moscow, close to the same latitude as Moscow though. When you search for Mordovia prisons, about ten show up with a big concentration of them at this location:
54.417877°N, 42.851292°E
Mordovia is not in Siberia and it is rather south as Russia goes.
She could be send in worse place!
