If you bought a used MBA online and the seller does not know the password, it is stolen. Seller probably stole it from a public place. Report it and get your money back. Don't wait too long, time is not your friend.

That's a bold assumption. There are many possible reasons for not knowing the password. It was a gift. It was a family member's computer that he bought but now can't afford to keep and that family member isn't currently available. He buys and sells many computers - he bought this one and then discovered it needed a password so he sold it. He has several computers and simply forgot the password to that one since he rarely used it (you've never forgotten a password?). He's helping an elderly relative dispose of the electronics of a dead spouse (so the relative doesn't know the password). I'm sure there are many other innocent possibilities.
Yes, it could still be stolen but it's hardly the only possible explanation.
