This kind of referendum is a joke.
Just some observations:
Pretty much only the pro-Russian people are left.
Ukrainian left these areas ahead of Russian attacks, hiding in underground, forcibly relocated to Russia or were killed by the Russians.
These areas are pretty empty now.
Referendum on zoom - world first!
Many people do not even have computers or internet. Fairness is totally out of question.
What happen to you if you vote No?
Siberia!
None of this is true. Turn off your television.
