I am just making buyers aware that they need to see a proof that you have turned off 2-factor authentication before you sell it to them.
Lifetime warranty or escrow will not help if you disappear from this site after 3 months
I don't use two factor authentification, and i not dissppear after 3 months
That doesn't guarantee anything. Your currently have a bad state of trust on the forum. And we all know these accounts are very likely hacked and resold. Unless you have a definite way of proofing you are the real and original owner of the account, these accounts were 100% hacked
The accounts can be easily charged back through their support and because of that, many people got scammed already. It is as easy as just sending an email from the email that registered that account and you can have that account charged back.
You can try accepting an escrow that will hold the funds for a time span that you will guarantee that the accounts will work. And the escrow will release the funds to you when the accounts still worked after that timespan (1-2 months) - so no selling, but renting out your accounts.
