Which is reasonable. If you pay for something, you generally are at least slightly responsible for it. Just because you don't want to be responsible for it doesn't mean you aren't.
For example, if I buy a car, hand the keys to a friend, and they go out and commit a crime with the car, I'm going to bet that I'm legally culpable in some fashion.
Are you saying that Bogdan did anything other than pay for the account? (Which seems a mite expensive, but I've given relatives more expensive things every year as far back as I can remember, so I'm not going to call that implausible.)
Legally, in most US states... it would be a stretch. The prosecutor would have to prove that the lender reasonably expected their friend to commit the crime.
FWIW, I've lent firearms to people on multiple occasions, sometimes for months or years at a stretch.
