Question about steam accounts

[Nightkid3]

I don't understand much about steams so i have a question. When you buy an account, how are you sure that the seller will not "retrieve a lost account" ?

well there is no way to make sure that they don't retrieve, if they have the original CD-KEY or paypal, credit card #. they can retrieve the account.
