The buyers and sellers of the accounts are the issues. Keeping people safe as an escrow isn't something to be punished for, regardless of what they are escrowing.
Ignoring all of the above, I generally do not like telling other people what kind of transactions they can and cannot take part of, when all parties to the transaction are fully understanding of the consequences of the transaction. Attempts to regulate these kinds of transactions is nothing more than a power grab.
What a silly thing to say.
