I think you and I move in very different social circles...
I would have no idea how, nor desire to purchase a Google account on the black market, and I do in fact still trust that my web browser can do TLS correctly.
Sure but how do I know that the person I'm buying from legitimately owns the account? Won't scam me? Or try to con me out of my existing account? I'm just saying not everyone is as relaxed about that sort of thing.
VK has been digging its own grave for quite some time now. Hardly anyone uses it any more. It's speedrunning enshittification with that registration thing but also with the very unpopular post redesign, the removal of custom news feeds, and most recently with shutting off most of the API access for third-party apps, including popular client apps like Kate Mobile.
