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.
Definitely true all that is contained here because, one can not truly give off an account that bares their individual details or it's tied to them to a third party for which ever use the third party hopes to do with this account. For this reason, the best way to stay clear of any menace committed with this account is to have acquired account through the means as at above and as such, your legally obliterated from the crimes that comes with it because, most of this bought accounts are targeted at criming or accessing services for which is supposed to be legally denied.
For these reasons, majors are put in place before sales of this form is allowed on the forum. Threads or posts aren't just deleted for the fun of it, it doesn't make sense.
