@9to5Mac reminds me of how around the time I quit my job at VKontakte in 2016 because of the new management, there were some new hires whose account IDs were 200M+. Very very new accounts. I'm certain some of them signed up for the thing just because they had to, you know, use the product of the company they're working at. Also because all our internal communication was on VK itself. They used Facebook and Instagram for their personal stuff.
