Since you were running a store that sells accounts for services that require KYC, there is only a small number of ways you could've acquired said accounts. You:
1. Hacked them.
2. Passed KYC with stolen documents.
3. Passed KYC with fake (counterfeit) or modified expired documents.
4. Passed KYC with documents bought from their owners.
All 4 methods are widely illegal. And as per the "Hacked invites/accounts are not allowed" stickied "Invites & Accounts" topic:
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.
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.
