Sorry, but it's very naive to think that Russian people use only "allowed" crypto exchanges and comply with the laws. That would be an impossible country to live in.
Direct connections with people and being street-smart are important kinds of skills in such societies. And even without connections, you can easily go to some popular Russian exchange aggregators and find no-KYC options with cash delivery, as far as I know.
EDIT: I've actually just checked for you: starting from 10,000 USDT, you can cash out anonymously with cash delivery for 1% in Moscow right at this moment from a publicly accessible resource with reviews.
