I didn't handle it, but it being against the terms of their site wouldn't mean it's not allowed here.
Selling hacked accounts isn't allowed, and since this user didn't explain why the
KYC-verified account isn't hacked, it
's not allowed
to sell this on Bitcointalk
and the seller should be banned:
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.
You are only allowed to sell accounts/invites that you legally obtained yourself or through legitimate trades. If you did anything illegal in order to obtain an item, then you can't trade it on bitcointalk.org. Anyone found breaking this rule will be banned.
