Whenever me or people I know were contacted by a person claiming to be a pollster, including Levada, we just hang up.

Nobody risks a chance of being "tested" by FSB or "anti-extremist" operative. The risk is huge from being put on control to personal harrassment by unmarked men spray painting "Z" and "traitor" on your door.

The only people who actually take a chance are those who say "we support special operation" anyway.
