These kind of posts pop up semi-regularly, with people selling hacked bank accounts, credit cards, Paypal/Skrill/Neteller/etc accounts, stolen documents, and so forth. Given that selling any of these constitutes fraud, which is illegal in every jurisdiction (as far as I know), this is against forum rules:
17. Trading of goods that are illegal in the seller's or buyer's country is forbidden.
Usually I just report these users for offering illegal trades/services, and they quickly get nuked. I've reported the post you linked to.
Edit: The account's been nuked.
