That sounds like a valid theory, but it does not explain her account's connection to instances of fraud dating back to 2016.
It is really puzzling to see a genuinely talented artist entangled in such shady things, more so as she brings forward an even stranger story as an explanation.
But yes, the account did get banned before the "purchase" and was immediately un-banned afterwards, as @andrianna confirmed her vk.com profile.
Why exactly she did get banned again recently, I have no confirmation for that as of yet.
