You're providing accounts which require KYC, to be able to provide that you'll need to prove that they have been legitimately created, and not hacked. Here's the quote from theymos which clears this up:
Accounts on sites that require KYC such as bank accounts, PayPal, etc. are assumed to be hacked unless you explain why they're not hacked.
Therefore, to be able to sell these accounts without a moderator taking action, you'll need to provide a compelling reason to why they aren't hacked, because by default they're assumed hacked. Let's face it, most accounts that require KYC to be opened, are either hacked or opened illegally, because how else would you be able to do it? Obviously, there might be some ways for certain services, but we aren't going to know that necessarily, unless you give an explanation.
That doesn't mean you can just claim they aren't stolen or opened via fraudulent documents. You ideally need to prove they aren't to be able to offer them to be given a exception against the rule.
